Why rock climbing is the best sport?

Rock climbing can help you get stronger in a relatively short amount of time. It builds strength in your core, gives you strong abs, builds your back and arms, and is an overall great workout.

Many people think that climbing only really involves your back and your forearms, and while those muscles do play a large role in climbing, they are not the only muscles that are used.

Other muscles that are used and strengthened in climbing are:

1. Legs
2. Chest
3. Triceps
4. Shoulders

In addition to just building muscle and strengthening the body, climbing is also a great mental challenge. Whether it's getting over your fear of heights, or solving the puzzle which is the route, climbing really does involve a lot of mental power to help you finish the routes.
In bouldering, you must understand the route and how to climb it, often times as efficiently as possible, a task which isn't always as easy as it sounds, as there can be many different ways to climb it.

Also, climbing is a very social and accepting sport, an aspect that I personally was very surprised at as I have not encountered this before. While bouldering, you will probably always find someone to climb with and work on a problem with, which really helps both of you improve and progress in the sport.
