Strengthens Your Muscles: Rock climbing uses virtually every major muscle group in your body, making it a great whole-body workout. Rock climbing is a low-impact exercise, which means it is easier on your body, particularly your joints, while still being a great full-body workout.
Combats Chronic Disease: Research has proven that 20 minutes or longer of any high intensity activity significantly reduces risk of developing chronic conditions such as hypertension, type 2 diabetes etc. Rock climbing has been shown to be an effective way to battle chronic stress, thus reducing chances of developing stress related ailments.
Improves Your Flexibility: The range of motion involved in a climbing route demands flexibility as it requires climbers to reach, leap and climb to handholds and footholds usually far from a comfortable distance.
Improves stamina and endurance: Although the movements in climbing are relatively low impact but its the combination of the sheer mental focus, muscle strength and risk taking abilities that make a climber hold on longer, tighter than they ever expect to. This increases stamina and builds endurance because when your life depends on it, you push yourself to that out of reach hold.
Low impact on your body: Like any other extreme adventure climbing possesses inherent risks of bodily injuries. The body movements in climbing are rarely repetitive and all the movements that do happen are relatively low impact. There may be the occasional aggressive moves; but those don’t happen often so the impact on the body is negligible.
