The reasons why prisoners in American prisons are keen on fitness are as follows:

1. Exercise is to avoid starvation, and the calories of meals in American prisons are not low. Ensuring nutrition and health is a basic human right. No matter how bad criminals are, they can't be mistreated in this respect, otherwise the prison management will be sued. You have to have money if you want to stay in shape. Everyone in American prisons has a hobby of fitness. If you are not big, you will starve, and if you are hungry, you want to exercise.

2. Protect yourself. When I first entered the prison, I was surrounded by veterans, perverts and lunatics. I was just a very thin hooligan.

3. Make plans after getting out of prison. The significance of fitness in prison is equivalent to pre-job training outside. Get the perfect muscles in prison, and you will become a fitness expert outside.

4. Personal hobbies. In prison, you have plenty of time. Instead of wasting it, you might as well do something meaningful. Fitness is a very worthwhile thing.

Exercise misunderstanding:

1. Take a large amount of exercise and intensive exercise at the beginning.

Sudden large-scale exercise makes it difficult for the body to adapt, which may lead to severe fatigue, aching all over or old illness, and may also cause tendon and muscle strain, making it difficult to persist in long-term exercise.

the correct exercise method is: start with a small amount of exercise, a small amplitude and simple movements, so that the body can have an adaptation process, which is also called fatigue period, about half a month, and then gradually increase the amount of exercise and increase the amplitude, and the movements should gradually change from easy to difficult.

2. It's the first time to do equipment exercise, and I think that only by doing all the equipment once can I get exercise.

in fact, it is absolutely unnecessary to do the equipment one by one every time you exercise. That not only takes up a lot of your time, but also makes it difficult to persist in normal exercise because of sudden excessive and strong exercise. The correct way is to ask a fitness instructor or make an optimal exercise plan according to your own situation, and realize your fitness plan step by step in a planned way.

3. As long as you exercise more and don't have to control your diet, you can lose weight.

This method can only achieve the balance of calories in and out or not increase obesity. In fact, drinking sweet drinks, eating cakes and dried fruits, especially dried fruits that can squeeze out oil and foods with high calories, can wipe out your hard-earned weight loss achievements. Therefore, in order to achieve a lasting weight loss effect, in addition to exercise, we should also make reasonable regulation on diet.
