is rock climbing hard on the body?

Rock climbing can be physically demanding and challenging on the body. It requires strength, flexibility, endurance, and coordination. The intensity of the climbing experience can vary depending on the difficulty of the routes or problems you attempt. While it is a great way to build strength and improve overall fitness, it can also put strain on your muscles, tendons, and joints. Proper warm-up, stretching, and gradual progression in difficulty are essential to minimize the risk of injuries.

It can be pretty difficult and hard an you, but it really depends on how good you are at listening to your body and giving it the amount of rest it needs.

If you can do this well enough, climbing won't be that hard on you, it will just be hard in general, as a sport.
