Hello, I practiced in the gym for a year. My personal feeling is to get used to all kinds of musical instruments first. There are coaches in the gym who can guide and correct your movements. I'll get used to it first, then run for five or six minutes, sweat a little, and then I can do muscle stretching. I do six groups of eight to ten times for each part, one part a day. The first day is chest, the second day is back, the third day is shoulder, and the fourth day is two arms and three arms. The fifth day, legs. Then rest for a day or two. Because the coach will leave you alone after giving you guidance, except for personal education. So I'm basically on my own, and I'm basically doing okay now. It's just that the muscles don't feel as hard as the coach. Because I didn't take any supplements. Fitness mainly depends on persistence. As long as you work hard, you will definitely have a good figure.
