Rock climbing. This is definitely a recommended project. The sooner you start, the better. Once you like it, you will feel that your life is complete. I have been climbing for a year. With the progress of technology, it is more and more difficult to climb the route, but there are always new challenges, so I will never get tired of it and always look forward to the weekend. The once boring life suddenly enriched. And for physical exercise, rock climbing is an almost perfect project. It exercises the muscles of the whole body. Beginners think that as long as their arms are strong, they can climb high (and the quality of rock climbing has nothing to do with the level of rock climbing). On the contrary, it is not necessarily good to pull a hundred pull-ups in the gym. The bigger the muscle mass, the heavier it is. On the contrary, climbers are very thin and can't see muscles. You can watch videos. So what muscles do you exercise? Fingers are obvious. You don't need big fingers for general sports, but you do need finger strength for rock climbing. The forearm will develop into graceful fine muscles. Biceps is not very big, because rock climbing is not pull-ups, nor is it to grow muscles and look good. Small fine lines will obviously appear in the back muscles, which is very beautiful. Waist and abdomen are the core and the strength needed for rock climbing, so the promotion is also obvious. Not to mention legs, this sport requires a lot of legs (not in line with beginners' cognition, but legs and feet are the standard of rock climbing), and I will lose my legs. My jeans have never lost weight in the past 24 years. What benefits me is rock climbing. Thank you. Besides, rock climbing is good for the brain. Rock climbers like it because it has a wide range of charm. Different lines have different styles, just like doing math problems, you can solve them in the alignment garden. Even if someone has better physical quality and skills than you, you can't climb without thinking correctly. Actions are actions that everyone knows, but they just can't be done or can't be thought of at all. Therefore, this is really a game of wits and wits. People who have experienced it all say that once they like it, it's hard to give up. But why give up? This is a part of life.
