Gym climbing is a popular indoor activity that involves climbing artificial rock walls. These walls are equipped with various holds and routes, allowing climbers of all skill levels to practice their techniques in a controlled environment. Climbers use harnesses and ropes for safety, or they may climb on bouldering walls, which are shorter and do not require ropes. Climbing gyms often offer classes and training sessions to help beginners learn the basics, such as proper techniques and safety measures. Many gyms also host competitions, fostering a sense of community among climbers and encouraging them to improve their skills.
