How to improve at indoor rock climbing
Warm up before you climb.
Taking time to warm up and stretch your muscles before you start a climb can help to prevent injuries. Warming up and stretching may also help to improve your performance, so it is important to start every climb with a few minutes of cardiovascular exercise and some good stretching.
Try walking briskly or jogging back and forth in the gym for a few minutes to get your blood flowing. Stretch your arms, shoulders, core, and legs before you start your climb.
