My girl still lacked push-ups and pull-ups a few years before her body mass index was too low. I've never done it in my life. I have also read some articles and books, including fitness without equipment, and I feel that it is too suitable for me-too strong. Even if there are too few basic fitness programs, I will keep exercising. The first two weeks of the stair group should be high-frequency and low-intensity training, but it is basically low-frequency and high-intensity for me, although I have made my own training plan to face it.
"Prisoner's Fitness" is much more practical. Anyone can really do LV 14 moves. Although I haven't been promoted to LV2 for almost two months, I feel that my physical strength will be improved and I am too tired.
Meanwhile, it is said that fitness without equipment is good, but it is great. My goal is that this book is only for people with a fixed foundation. On the other hand, for strong people, there are only six movements for prisoners to exercise, and various variants seem a bit boring.
Besides, I think some things in the book are too much. Anyway, it has nothing to do with sports itself. Ignore it.
