Bouldering

Requiring neither a harness nor a rope, bouldering involves routes that are close to the ground. A thick crash pad acts as a protective mat below you. Some gyms also require spotters, people who help prevent falls from injuring your head and neck.

Bouldering is a great way to build skill because you can focus solely on using your strength and balance to keep yourself on the wall. Novices appreciate the simplicity of it; skilled climbers like the challenge of more difficult routes.
