Jake Lorimer is a lot like other 12 year olds, except for the fact that he can do things on a scooter that defy imagination.

Lorimer’s flips, spins and grinds are otherworldly when you realize he’s performing all these stunts on a tiny scooter that is usually retired when a kid finally upgrades to a bike or skateboard. He has spent the last year traveling to various Birmingham, England, skate parks with other extreme scooter pros. He’s also trying to find a sponsor as continues to compete in professional competitions and tournaments. He dreams of locking down a sponsorship to become an official extreme scooter pro.

Lorimer, however, isn’t giving up, even if he’s gotten dinged up while attempting tricks others would be too scared to try. That is the Adrenalist way.

No wheels, no water, no snow, no problem.

Those are the characteristics you can expect from brushboarding, an innovative new sport that allows you to ride in a completely new way: down a quarter-pipe constructed of quickly rotating brushes. The carpet of rotating round brushes recreates the sensation of dropping in on a wave or quarter-pipe. The wave-simulating technology can serve as instantly-accessible training applications for athletes. Instead of flying around the world, chasing ideal conditions, Adrenalists can simulate the waves they’re looking for and hit the brushes in order to stay on their game. On top of that, brushboarding can provide a supplemental workout to help build core strength and fitness.

New opportunities to brushboard are burgeoning, spreading from roots in the U.K. This week, Europe’s top surf, skate and music festival, Sea Sessions, will be hosting the sport amidst partying and competition. The brush ramp will also challenge Adrenalists at the new Airkix indoor skydiving center in Basingstoke.

It may be tempting for some to brush off brushboarding as a toy or a fad, but remember that many people have done extraordinary things with other up and coming sports. Sports like bag jumping, ice cross and even skateboarding, in fact, were all thought to be fads. We have a feeling that brushboarding will continue to grow, not just as a tool, but as an entirely new sport.

Cave jumping infuses our raw fear of the unknown with adrenaline to produce an extreme sport unlike any other.

There’s something primordial about jumping into a dark pit that leads to an unseeable bottom. That, however, hasn’t stopped a bunch of daredevils from taking the dive into the dark abyss around the world.

Check out the 5 best cave jump videos below and decide whether or not diving into the unknown is your next extreme hobby.

Marmet Cave, Croatia

You’ve probably heard of our first cave jumper before. Long before Felix Baumgartner was jumping from space, he was just like any other skydiver and BASE jumper, albeit one of those adventure seekers who dares to try whatappears impossible.

In 2004, Felix jumped into the Marmet Cave in Croatia’s Velebit National Park, which spans most of the Velebit Mountain range and features hundreds of holes. These holes are the deepest caves in all of Croatia, and Felix decided to try plunging into one of the more audaciousness. Marmet Cave, which is located in the Paklenica Park River canyon, is not an easy jump. Paklenica features 39 pits and 37 caves, and Marmet appears to be the only one anyone has ever jumped into.

In the video above, take a look at the opening montage as the camera pans down on Felix as he comprehends the mouth of Marmet. The gaping hole of black is exactly what we mean when we talk about the danger and the psychological turmoil cave jumping entails.

Grotta Gigante, Italy

The Grotta Gigante is a huge cave on the Italian side of the “Trieste Carso” in the municipality of Sgonico on the border with Solvenia. The central cavern is considered the largest tourist cave in the world and measures 107 m (351 ft) high, 65 m (213 ft) wide and 130 m (430 ft) long.

Because the Grotta Gigante is so large, it’s an ideal location for tourists to check out the wonderful collection of stalactites and stalagmites, which protrude from the cavern wall in wonderful patterns and shapes.

With all of our videos on this list, only Italian BASE jumper David Cusanelli’s cave vault is actually from inside the cave. As we mentioned, this cave is 351 ft high. In the case of where he’s jumping, it’s actually a little smaller at 323 ft in the air from the platform he’s stepping from.

The height of the jump is just enough to allow Cusanelli time to get his chute open before landing on the dangerous, millennia-old stalagmites and stalactites. Watch as he pulls his chute immediately after jumping off the specially designed platform.

This jump is actually fairly recent. Cusanelli pulled this off earlier in June and it’s a bit unnerving to watch the Italian BASE jumper pause for so long as he looks down the claustrophobic path he must take. Even though the Grotta Gigante is the world’s largest tourist cave, it’s still a cave, and not the ideal environment to BASE jump.

Cusanelli’s parachute opens and just a couple seconds later he’s landing. He lands the only cave jump on this list from inside a cave.

Xiaozhai Tiankeng Sinkhole, China

In China, there are sinkholes due to natural erosion caused by dissolution of carbonate rocks, suffosion in sandstone or collapses of old mines. Regardless of how they formed, they’re breathtaking in their scope. The largest sinkhole in the world is China’s Xiaozhai Tiankeng, in the Chongqing district. Some refer to it as “the Great Sky Hole,” because you can actually notice it’s vastness only from aerial shots.

Measuring 626 m long (2053 ft), 537 m wide (1762 ft) and between 511 to 662 m (1676-2172 ft) deep, Tiankeng literally translates to “heavenly pit.”

In 2009, Chuck Berry, along with a group of 21 other experienced BASE jumpers from over 12 different nationalities jumped into the “heavenly pit.” BASE jumping into the world’s largest sinkhole, however, isn’t simple

This cave jump makes your adrenal glands pulsate, but Chuck and his team figured out the best possible way to accomplish the jump was by using the leftover cable to pulley out to the center of the sinkhole. This allowed them to get the maximum amount of distance into the center of the sinkhole’s seemingly endless bottom.

Majlis al Jinn, Oman

This next cave, the Majlis Al Jinn in Oman, is the ninth largest cave chamber in the world, but the largest in the Middle East. It was only discovered in Oman in 1983 about 100 kilometers southeast of Muscat.

Despite it’s relatively recent discovery, two BASE jumpers went free falling into the surprisingly large cavern deposit; the enormity of the cave’s chamber comes despite such a narrow mouth to that chamber. Majilis al Jinn is a single chamber cave with three openings at the top, with an interior measuring 310-225 m (1017-738 ft) and a domed ceiling measuring 120 m (393 ft) high.

The first video comes from three months ago, courtesy of the Skydive Dubai team. The videographer and producer, John Falchetto, documented the setup, as Skydive Dubai team members Matt, Chris, Noah and Mike actually jumped into the cave with just a parachute on their backs.

Noah was the first to jump, and he decided to backflip into the narrow mouth of Majlis al Jinn before almost immediately yanking on his chute’s cord as he lazily drifted to the bottom of the cavern’s chamber.

The second video features British world class climber, alpinist, BASE jumper and overall adventurer, Leo Houlding. Leo jumped the Majlis al Jinn a couple years ago as a part of the British reality adventure series, “Take Me to the Edge,” which he hosted.

Both the Skydive Dubai group and Leo completed a cave jump unlike any other.

Cave of Swallows, Mexico

The Cave of Swallows is an open air pit in Mexico’s municipality of Aquismon in the San Luis Potosi State. The cave itself was formed by water erosion along a fault in the limestone forming a conical descent. The Cave of Swallows has been known for longer than some of the other caves featured here. It was discovered in 1966 by T. R. Evans, Charles Borland and Randy Stern.

The name does not derive from the feeling of being swallowed by the earth whole. No, the Cave of Swallows is named after the birds who nest along the cave’s walls and fly out of the upper opening to search for food during the day.

The mouth of the cave forms an elliptical shape measuring 49 by 62 m (160 by 203 ft) wide and is undercut as you go down. The actual chamber of the cave measures 303 by 135 m (994 by 442 ft) wide.

It’s a 333 m (1092 ft) freefall drop from the lowest side of the opening, with a 370 m (1,214 ft) drop from the highest side, which makes it the largest known cave shaft in the world and the second deepest pit in Mexico. New York City’s Chrysler Building could fit in the cave. A person without a parachute would take almost 10 seconds to free fall from the cave opening to the floor below.

In February of 2004, the Phoenix Fly team traveled to Mexico for an expedition of BASE jump outposts in Mexico. Obviously, the Cave of Swallows was their focal point, but they weren’t planning on jumping without a parachute.

The Phoenix Fly team members jump in tandem and one after another, so you get the perspective of free falling into the cave while someone is falling right on top of you.

The art of BMX should be surrounded by a landscape as jaw-dropping as the skill involved in perfecting the sport, and Lofoten’s beauty is unrivaled.

The Lofoten, Norway, archipelago runs between the 68 and 69 parallels at the top of Norway above the Arctic Circle. Despite its location, temperatures soar in the summer and the 24-hour days in between the months of May and June are some of the driest areas on earth despite being surrounded by water. That lack of night is why they hold the Lofoten Insomnia Race every year in mid-summer during the 24 hours of sunlight along the entirety of the Lofoten archipelago.

It’s also why the Lines of Lofoten project manager, Vegeir Selboe, decided to build a dirt line and a big bike line in the breathtakingly beautiful Lofoten. Selboe also helped produce the Lines of Lofoten web series, directed by Niels Windfeldt. The series of five mini-movies, which you can now on Antimedia’s Vimeo page, track the progress of their construction. The goal of the project was to construct ramps and jumps on a BMX line that combines the splendor of Lofoten’s pastoral beauty with world-class BMX riding from Adrian Tell, Kristoffer Haugland, Didrik Dege Dimmen, Niclas Andersen, and Nico Vink. With only three weeks to complete the upper and lower lines and with the fast-shifting weather in the area causing havoc on the construction, however, Windfeldt only had a few days to film once the lines had been completed.

The project was worth the headaches.

=With the riders ripping no hand backflips, can-cans, Supermans and many more big air tricks while heading down towards the sand and sea (the BMX line actually ends at the ocean after the series of jumps), you can’t help but gasp at what was accomplished. Just like the crazy BMX dirt jumps session Jaie Toohey and Jed Mildon pulled off in Australia, this is an extreme display we can watch again and again.

Trail riding encompasses a number of obstacles unseen by the traditional cyclist or BMX rider, but what a pro can pull off on the trail is nothing less than supernatural.

There’s a reason riders James Doerfling and Linden Feniak refer to themselves as the “trail wizards.” As you can see in their latest video, Welcome the Trail Wizard, Feniak and Doerfling use their trail riding wizardry to tear up the Sunshine Coast in British Columbia. The five-minute film, put together by a team of awesome sponsors including Joystick Bicycle Components, Knolly and SR SUNTOUR, gloriously captures the effortless thrill and thrash of mountain bike trail riding.

Riding like this isn’t easy, but with the right bike and a little practice, you too can ride the trail. It’ll take a bit more than that to ride like Feniak and Doerfling, though. Brush up on your magic and maybe you’ll be able to ride like these Adrenalists.

Humans may not be the quickest creatures around, but we can put up a good fight.

Peregrine falcons are the fastest animals on earth, reaching speeds of more than 200 mph during their high speed hunting dives. Mountain bike racer, Gee Atherton, will never go quite that fast, but that doesn’t mean he can’t outride the falcon down a mountain in Antur Stiniog, North Wales, before the bird can snatch a bag of fresh meat from Atherton’s back.

“I’m going to be riding fast downhill. There’s jumps, there’s drops, there’s turns,” Atherton says before his run. “Hopefully I’m going to be able to stay ahead of the bird and keep away from it.”

You’ll have to watch the video to see who wins this interspecies showdown. Filmed with ten cameras, including a bird cam, sky cam and head cam, and executed flawlessly in a harsh environment, this video stunt produced by BBC Earth Unplugged, Gee Atherton and Red Bull is an adrenaline boost of the most creative kind.

Check out a behind-the-scenes video for more on the stunt, and follow Gee Atherton on Twitter to find out who or what he might race next.

As we develop new ways to explore and engage in extreme sports, it’s necessary to look back and see how far we’ve come from time to time.

What would our ancestors think of modern athletes, with their outrageous speed, strength and general fitness? Watching athletes compete at the top of their game is entertaining because what they do is not just unique, but incredibly difficult to boot. Between then and now, we have evolved tremendously in sport. It becomes even more impressive when we consider the gains that have been made in just the last hundred years.

Here are a few examples of just how far we’ve come and how much we’ve improved.

The Marathon

The modern marathon race stems from the myth that, after the Greek victory over the Persians at the Battle of Marathon, a soldier who fought in the battle ran all the way back to Athens to inform the people of the victory. Legend says that he arrived, shouted, “we won,” and died of exhaustion.

The first modern marathon was held in 1896 and was won by a Greek amateur, Spyridon Louis. It took him about three hours and he ran from the actual site of the battle of Marathon to Athens. Half way through the race Louis stopped in a village pub for a glass of refreshing wine. He then continued on to the stadium where the local crowd was so ecstatic that two princes ran the final lap with him and the king offered him any gift he desired.

Things have changed a lot. The current record for the men’s marathon stands 2:06:32. That’s right, an improvement of about a third. Now, the victor of the first Marathon ever wouldn’t even make the qualifiers for modern races. Fauja Singh, the oldest marathon runner ever, raced his last marathon ever this year at age 101, and Ultra Marathon Man Dean Karnazes is said to be able to run at a seven to ten-minute per mile pace forever.

Where did this big improvement come from? Modern sports science has taught us more about the human body and how to maximize its potential. Modern nutrition means that we grow up with the potential to be healthier, stronger and taller than any previous generation. Additionally, the fact that you can make a living being a professional athlete now (Spyridon Louis was a water carrier) means more time to train.

The 4-minute mile

The four-minute mile use to be considered impossible. Now, it is routine for top runners and has even been accomplished by several high school students in the US. It is has become so common that even some runners over 40 have made the mark. Runner, Daniel Komen, even made two miles in under 8 minutes. The current mile record is held by Hicham El Guerrouj of Morocco, at 3:43.13.

All of this was once thought impossible. In 1945, Gunder Hagg of Sweden set the world record at just one second over 4 minutes. It took another 9 years for someone to beat that, and that man was Roger Bannister, an Oxford medical student. Check out Bannister in the amazing footage above. It’s no accident that this magic barrier was broken by a medical student. Not only did he train hard, he used his scientific knowledge to do experiments and learn more about the mechanics of running. He optimized his nutrition and methods with science and managed to break the 4 minute mark for the first time. Once this knowledge was out in the open, it didn’t take long for that record to be broken. In the half century since, the record has gone down by 17 seconds. This isn’t quite as dramatic as the marathon, but it’s in a much shorter event.

Again, how did we arrive at such super human speeds? The answer, as the medical student who broke the record realized, is science. From those innovations emerged the fields of sport science and sport medicine. This research has driven gains through the athletic world. What use to be impossible is now routine.

Rock climbing

There are many examples here, but perhaps the most iconic is El Capitan in Yosemite. In yet another example of naysayers consistently being proved wrong, people use to say it was impossible to climb El Capitan. The very first summit of the mountain took 47 days. It involved lots of assisted climbing, drilling into the rock, placing expansion bolts and slowly making progress. Today, competent climbers can do it in 5 days.

The really astounding accomplishments have been made by professional climbers who free solo various routes in under a day, often in a few hours. From 47 days to a few hours, that’s a tremendous improvement. Every few weeks it seems an Adrenalist has broken a new record or finished an impossible climbing feat. Recently, Adam Ondra became the first climber to conquer La Dura Dura, and the treacherous Laila Peak was scaled for the first time in winter.

Everest without Oxygen

In 1953, Edmund Hillary and Tenzing Norgay became the first people to successfully climb the tallest mountain on earth. This was an amazing accomplishment, and it shows you just how far we’ve come. It wasn’t until 1953 that humans had succeeded in making it to such places. One of the big aids to this climbing team were routes and trails established by the previous climbers, not to mention the caches of oxygen left behind. Relying on these leftover caches seemed like the only way to make it to the top of Everest and through the so called “death zone,” an area where there is only 1/3 as much oxygen as at sea level. With such little oxygen in the blood, it’s possible to become exhausted just from breathing. Low oxygen results in a decline in mental ability, making it difficult to think clearly and make the split-second decisions necessary at the top of the world. It takes weeks to acclimatize, and it used to be thought that making the summit was only possible with the help of bottled oxygen.

25 years after the first summit, however, Reinhold Messner made the ascent with no oxygen assistance. When critics claimed he’d snuck oxygen he proved them wrong by summiting solo and with no oxygen on the harder route. From there it became routine for elite climbers to do the climb without oxygen. It only took 25 years from the first successful assent for an Adrenalist to climb Everest alone with no oxygen. That’s the essence of human beings pushing the limits of what’s possible.

Flight

For most of history we have been firmly stuck to the ground, only dreaming of flight. In 1903, the Wright brothers invented mechanical flight, but it still wasn’t enough for those most intrepid adventurers. Adrenalists wanted to fly on their own. Very soon after, men began to jump out of those flying machines. Thus began the evolution of the parachute, from the old canopy style to the modern paragliding designs. Today, you can sore like a bird in a hang glider or a paraglider. That, by itself, is impressive, but that still wasn’t enough for modern adventurers, however, as they didn’t want a machine, a canopy or a glider to aid them. They wanted to fly with their own bodies. Finally, the wingsuit was born.

These suits add lift with webbing between the legs and under the arms allow people to achieve a gliding efficiency of up to 2.5. That means, that for every foot you fall, you move forward 2.5 feet.

One of the most popular manifestations of this technology is proximity flying, which involves BASE jumping with a wingsuit, then flying close to the cliff edge and flying through waterfalls, rock arches and hitting targets. This sport continues to grow and be explored. It’s as close as a human being can get to flying without a machine.

It is, however, still extremely dangerous. In 2011 alone, 10 people were mortally wounded in wingsuit accidents. That hasn’t stopped Adrenalists from continuing to do it, because it’s the ultimate thrill. Just check out Jokke Sommer soaring through skyscrapers in Rio or Alexander Polli’s wingsuit target strike.

Wingsuiting is one of the ultimate examples of how far human abilities have been pushed. 60 years ago, the dream of running a marathon in 2 hours or a mile in under 4 minutes, climbing Everest with or without oxygen, or of flying through the air like a bird, were just that: dreams. During that time science, technology, training and sheer will have brought human abilities to the edges of the world. Imagine what we’ll do in the next 60 years.

Hungry Adrenalists are always hunting for the next big record to break, and skydiving martial arts is the latest category to become the prey.

On May 23, black belt, skydiving instructor and military man, Ernie Torres, jumped from an airplane above Arizona and punched his way into history. With the help of a team of skydiving professionals, Torres punched through 12 pine boards while in freefall, smashing the previous record of seven boards broken by Jason David Frank earlier this year.

While breaking boards in mid-air may seem humorous, Torres maintains that his stunt was no joke. He hopes to use the publicity from the video to raise awareness and funds for the Wounded Warrior Project. Donate to the cause to provide comfort to an injured warrior returning home from armed conflict.

While the video proof appears to show Torres easily broke the record, Guinness has yet to make it official. In the meantime, check out the best GoPro skydiving videos for more skydiving insanity.

The Darien Gap is just about as rugged and extreme as it gets for the adventurous Adrenalist.

From the tip of Chile to Prudhoe Bay, Alaska, the Pan-American highway speeds along, uninterrupted, for thousands and thousands of miles. That is, except for one place: the Darien Gap. A section of jungle between Colombia and Panama, so rugged that building a road was deemed impractical. The Darien Gap is a crossing that is home to wild beasts, endless rivers, swamps, and dense stretches of rainforest. Not a fun place to get lost in, to say the least.

That, however, doesn’t mean that intrepid explorers, travelers and hikers don’t venture in. Some of the most epic and famous cross-continental adventures have crossed this short, yet treacherous, passage at the midpoint of their longer journeys. Now, the crossing is opening up to more tourism, and it’s possible for your average adventure seeker to make the voyage. The key is to have local guides, usually Kuna indians, and local knowledge. There are famous cases, from both the 19th century and 20th century, of explorers getting lost and fatally wounded in this wilderness.

The main danger is the jungle itself, full of poisonous snakes, sneaky jaguars, caimans and bugs that will leave your arm immobile and in pain. Make sure you have your poisonous animal bite survival guide handy for this journey.

Those risks, however, just add to the thrill. It’s a small price to pay to visit one of the ultimate untouched places. The Darien Gap is the only gap in the Pan-American in a world increasingly paved over and easily accessed.

If you’ve ever braved the Darien Gap or plan to take on the crossing soon, let us know in the comments below or @DegreeMen.

People with real superhuman qualities and powers are something we only see within the pages of glossy comic books, or are they?

Is it possible that real life people with superhuman powers can be walking among us?

Take a look at these Adrenalists, a handful of superhumans who defy conventional science and the odds.

The Ultra Marathon Man – Dean Karnazes

Running 26.2 miles (the length of your typical marathon) is an impressive feat for any person. The race stands as the ultimate test of endurance and physical and mental stamina and is often one of the defining moments of a person’s life.

The average person is usually immobilized from extreme soreness for a handful of days following running marathon, but not Dean Karnazes. After completing a marathon, he woke up the next day and did it all over again. He ran another marathon. Then he ran another and another. In total, Karnazes ran 50 marathons in each of the 50 U.S. states in 50 consecutive days. When he completed his last race, the New York City marathon, he decided to head back home to San Francisco. He did so by running there.

Karnazes is a decorated super-runner. In Oct. 2005, he spent three sleepless nights running more than 350 miles nonstop through Northern California raising money for charity as well as making a claim for the title one of the fittest men on the planet.

Karnazes possesses an uncanny ability to run incredible distances and is considered one of the fittest men on the planet. His capabilities have been tested by science and one study found that Karnazes’ muscles damage much less with exercise than a normal person’s does. His muscles actually get accustomed to continuous exercise and stop being damaged all together, meaning that over the course of his 50-marathon stint, his body adapted to his running schedule and his muscles experienced comparable strain running the 183.4 miles per week as they would walking the halls of an office job.

What makes this all possible can attributed to Karnazes having more blood in his circulatory system than the average person, which allows him to stay hydrated for longer. Medical testing concluded that Karnazes is a walking battery; as long as he stays properly hydrated and nourished, he can literally run at a seven to 10-minute per mile pace forever.

The Iceman – Wim Hof

Wim Hof has been baffling scientists for years. In temperatures that would be extreme torturous and fatal to the average human, Hof not only survives; he thrives in it.

They call him the Iceman.

This is a man who has climbed Mount Everest and Kilimanjaro in shorts and a T-shirt and told ABC News that it was “easy.”  He ran half a marathon above the Arctic Circle barefoot and in shorts, where the ground temperature was 35 degrees below. He also completed a full marathon above the Arctic Circle in shorts.

In total, Hof has 18 Guinness World Records. He took the world’s longest ice bath at 1 hour 52 minutes, shattering the record previously set by himself, his only real competition. Hof says on his website that his powers lie in meditation and anybody can learn it. He taught himself how to control his heart rate, breathing and blood circulation and essentially warm himself up from the inside out using his mind. Heart rate, breathing and blood circulation are regulated by the autonomic nervous system, where conventional scientific knowledge was that a person cannot consciously control it, but Hof can, baffling scientists everywhere.

Even while completely immersed in ice, Hof can regulate his core body temperature and maintain it at 98.6 degrees Fahrenheit. During Hof’s barefooted half marathon in arctic in 2007, he had a medic accompany him and she noticed deep into the race that Hof’s feet stopped receiving blood circulation. Hof finished the race anyway. He somehow was able to restore circulation into his feet, and walked away from the race and went on to compete in other incredible tests of physical and mental strength, leaving the medic and the whole science world for that matter, literally speechless.

Super Balance – Eskil Ronningsbakken

At age 18, Eskil ran off to the circus – literally.

This Adrenalist is sitting upside down on top of a bicycle suspended in the air in a Norwegian fjord more than 3,280 feet in the air on top of a wire. With just a small weight in place below for stability, one wrong move and it’s a long fall into the icy waters below. Add brisk winds and being miniscule clothing to the mix and you have one of the most extreme balancing and visually stimulating stunts performed by Eskil Ronningsbakken.

The Norwegian performer considers himself as an artist; he wants his death-defying balancing acts to serve as expressions of art versus stunts. Walking a tightrope between two hot-air balloons, perching on the edge of a cliff face on a unicycle, standing on a rope above a waterfall using a block of ice as a platform to stand on, balancing upside down on a chair on top of a cliff, mark just some of the incredible capabilities in Ronningsbakken’s repertoire.

Ronningsbakken has a real superhuman ability to not only balance at incredible heights, but he also makes a claim for being the man without fear. In a segment of The History Channel’s Superhumans that featured Ronningsbakken that you will see in the video above, he met with scientists who hooked up him to a heart monitoring machine and the scientists took readings of his heart rate when he was sitting in the room and again when he was balancing upside down on top of a chair on the edge of a 100-foot tall building. The body’s natural reaction to a fear-enduring situation is a faster heart rate; quickened blood pressure and breathing as well the release of the stress hormones adrenaline and cortisol. The results indicated Ronningsbakken’s heart rate was virtually the exact same, meaning he felt the same physically dangling upside down off the edge of a building as he did sitting in a chair.

Ronningsbakken uses his superhuman ability of living without fear to perform jaw-dropping visual performances and said using harnesses and safety nets are against his principles. His next stunt may be his biggest yet, as Ronningsbakken plans to balance on top of the tallest building of the world, the Burj in Dubai, United Arab Emirates.

In April 2013, Eskil added a new trick to his death-defying repertoire: he did it all blindfolded. Walking over a bridge more than 1,000 feet in the air is enough to make even us toughest Adrenalists nervous. Watch and marvel as Eskil amps up the wow-factor by performing his incredible talent with a blindfold.

Super Reflexes – Isao Machii

Isao Machii has the ability to use his real superhuman reflexes and sword skills to cut a BB gun pellet in half and slice an apple in mid-air.

The History Channel calls him a modern-day samurai, and has been perfecting his incredible swordsman skills since age 5. His years of sword training coupled with his lightning-fast reflexes make him able to perform unbelievable tricks using hand-eye coordination. In the Superhuman segment of The History Channel, his abilities were tested out at a firing range. As you will see in the above video, the BB gun was fired at Machii at a firing range and he drew his sword and sliced the pellet in half on the first try.

To put the feat into perspective, the BB gun shoots at 200 miles per hour. The BB gun pellet traveled too fast to be registered by the human eye. The experimenters heard the ping sound of the impact of the sword blade as it hit the pellet, though, and then reviewed the footage.

The average person would spend 3/10 of a second to just process the sound of the BB gun being shot before he or she could even begin to think about reacting. By the time the average person registered what is happening, the pellet would have passed them, which means Machii and his abilities take hand-eye coordination to a level previously thought not humanly possible.

Because an object traveling at 200 miles per hour is too fast for the human eye to register, Machii is operating on an entirely different sensory level. He is anticipating and processing when the pellet will arrive. Machii’s extreme reflexes make him able to predict not only where the object will be when it arrives, but when the object will get there as well.

The World’s Strongest Kid – Liam Hoekstra

Like most professionally-trained gymnasts, Liam Hoekstra has demonstrated athletic promise from a young age. Unlike most professionally trained gymnasts, Liam Hoekstra started performing a gymnastics move usually reserved for experts at 5 months old.

By 8 months, Liam could do a pull-up and by 9 months, he could climb the stairs. Liam’s incredible strength caught the attention of his adoptive parents, who brought him to a specialist, where he was then diagnosed with a rare condition called myostatin-related muscle hypertrophy.

While Liam is not the only documented case of super strength, there is a German boy who was born with a defective myostatin gene that showed super strength,but Gimundo reports that Liam is the first case in which there are no ill effects.

While Liam is just 3 years old, he has already garnered national attention from media and body builders alike. Liam’s family is limiting his media exposure at his young age in order for him to have a relatively normal childhood. But from a kid who can lift weights and perform Olympic-worthy feats before even graduating from the sandbox, “relatively” is the operative word for a kid with real superhuman strength.
