No, it’s not all the same!
Indoor climbing generally falls into three main categories, top roping, sport (lead), and bouldering. Each category has its own characteristics:
Top Roping: The climbing you see pictured here is top rope climbing. The rope is anchored above and belayed either manually (by a person) or automatically (by a machine) below. Belaying is simply when a person or machine maintains consistent tension to the rope so you are supported in the event of a fall. Your routes usually follow color coded “holds”( fake rocks) which have ratings but more on that later.
Sport (Lead) Climbing: In the case of indoor climbing, carabiners (locking clip used for climbing) are connected to pre-placed bolts on the wall. As you ascend the wall, you clip into the carabiners. These catch you in the event of a fall called a “whipper” in which you fall down to the last clipped carabiner . This method is usually more common among advanced routes in the gym.
Bouldering: Bouldering is the fastest growing form of indoor climbing in North America. Using spotters and crash pads (thick pads placed below the climber) instead of ropes, climbers traverse walls which are usually no more than 20 feet high. This category is focused on development of difficult transitions and techniques made in the safety of a short drop.
