Some time ago, I went to the gym to practice my legs, and every time I finished practicing my legs, I felt particularly uncomfortable. Then an uncle came to guide me. He told me some points for attention in leg exercise. I don't want to change my methods easily, so I didn't listen to him. Later, I found that I couldn't practice anymore. Later, I tried that uncle's method and found it particularly useful.
Later, when I chatted with my uncle, I realized that he had been exercising for more than 20 years, but I didn't see any signs of aging in him, because exercise and fitness made his youth pass more slowly. Later, my uncle also taught me a lot of experience in shoulder training and back training. Slowly, I found that standing on the shoulders of giants can see farther, which is also a convenient way. So later, according to the secret my uncle taught me, I found it easier and easier on the way to fitness.
So you must learn from others in the gym with an open mind. If you are embarrassed to ask, observe more. As long as you stay in the gym for a long time, you can easily become handsome. And as a boy, there may be a little girl following you all day. Then you can pass on your experience to her.
