Just as the name suggests, rock climbing is the sport or activity of climbing rocks — either natural rock formations or artificial climbing walls. The goal is simple: get from the bottom to the top without falling. How fun does that sound? Well, falling is actually part of the fun, too. The sport is both physically and mentally demanding, as it tests your strength, endurance, balance, flexibility, as well as mental control and problem-solving. It will also get your heart pumping.
