Climbing RopeRope climbing is a very simple exercise; in fact, it is probably one of the simplest exercises you will come across. Climbing will improve your functional grip strength, enhance cardio and improve upper body strength. Just like a pull up, rope climbs require you to move your entire body weight in one motion. Even if you incorporate your legs by pinching the rope with your feet, youre still moving more weight than you usually would with free weights.
