With warm weather starting to sweep in, it’s time to start getting yourself in shape for outdoor activities. Rock climbing enthusiasts can only do so much with a proper wall or cliff face to scale, but the GripSaver Plus from Metolius Climbing is designed to help you get your fingers limbered up before they can fail you in a more precarious location. Essentially a stress ball with five finger loops, the GripSaver Plus is designed specifically to help strengthen your hand, wrist, and forearm muscles.

Available in soft, regular, or hard versions straight from Metolius for $17.95.
