Have you ever seen Prisoner's Fitness?

I've read all three books, so I'll briefly talk about my personal opinion based on my own fitness experience.

Let's talk about the bad points first. For my own purposes, the author belittles modern fitness and equipment training in the gym. The limitation of self-weight is obvious. For example, many people can't do a few pull-ups that require the cooperation of multiple muscle groups. It may not be that their back strength is insufficient, but that other strength is insufficient, such as myself. I don't have enough grip, but the grip training in the book, that is, the way of using towels, is really slow. I went to learn how to do forehand bending with barbell, dumbbell hammer, and the way of twisting barbell with forearm force. The forearm is much thicker, which solves the problem of grip. Whether I do pull-ups or barbell dumbbells, it is much more convenient, which shows the limitation of self-weight. Self-weight training is a multi-joint and multi-muscle group exercise, but instrument training can make you exert your strength on individual muscles. This is the point.

There is also the author's lack of honesty. The so-called demonstration action of one-handed push-ups is against mechanics. There are three support points for one-handed push-ups, and the center is obviously beyond three o'clock. It is impossible not to spread your legs. You can see that Bruce Lee spreads his legs.

Let's talk about the good place. Self-respect training is indeed beyond the equipment, that is, comprehensive. As mentioned above, it is necessary for multiple muscle groups to cooperate, which will improve your physical performance. For example, parkour and street fitness are two extremely high levels of self-respect, such as violent climbing, horizontal bar front level, downwind flag and Russian standing. Many muscle men in the gym can't do these acrobatic moves, and self-respect training is available.

Physical exercise pursues different things. Some people, such as Parkour, pursue that kind of excitement, while others pursue physical beauty. There is no need to denigrate each other for their own purposes. For example, bodybuilders may say that Parkour people are in poor shape, while Parkour people will say that bodybuilders' muscles are useless, with different starting points and different pursuits, which is equivalent to telling chickens and ducks that there is nothing right or wrong. Why do they denigrate each other?
