Most people would not really think of rock climbing when they go to apply or sign up for a hobby. They would probably think of a more popular sort of sport like football or basketball. But rock climbing could just be the thing that you need when exercising. One man, Robert, said that he was quite unfit when he was a high school student until he took up rock climbing. Once he did take up climbing he started to get much healthier and physically fitter. Clearly showing that rock climbing can be used for all different kinds of purposes he went on to joining a group of climbers that now train often and are an experienced group of rock climbers.
Although, like any sport, rock climbing can be an extremely dangerous thing. You have to wear the correct safety gear for the climbs and have trained a lot depending on what kind of place you are climbing near. But, rock climbing can also be a friendship builder. You can join other people during climbing and become best friends. Just like all sports really. Except for maybe singles in tennis. But, you get the drift.
