1, exercise is to not be hungry, and the food in American prisons is not low in calories. Ensuring nutrition and health is a basic human right. No matter how bad the criminals are, they can't be mistreated in this respect, otherwise they will sue the prison management. If you want to keep fit, you must have money. Everyone in American prisons has a hobby of fitness. I'm hungry when I'm young, and I want to exercise when I'm hungry.

2. protect yourself. When I first entered prison, I was surrounded by veterans, perverts and lunatics. I'm just a thin hooligan.

3, in order to make plans after getting out of prison. The significance of fitness in prison is equivalent to pre-job training outside. When you build perfect muscles in prison, you will become a fitness expert outside.

4. Personal hobbies. In prison, you have plenty of time. It is better to do something meaningful than to waste it. Fitness is a very worthwhile thing.

Practice misunderstanding:

1, the initial exercise will take a lot of exercise, high-intensity exercise.

Sudden large-scale exercise makes it difficult for the body to adapt, which may lead to severe fatigue, body aches or recurrence of old diseases, and may also cause tendon and muscle strain, making it difficult to keep exercising for a long time.

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

2. The first time I do equipment exercise, I think all the equipment must be done once to get exercise.

In fact, there is absolutely no need to make equipment that can't land every time you exercise. That not only takes up a lot of your time, but also makes it difficult to maintain normal exercise because of sudden excessive and intense 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 achieve the goal of losing weight.

This method can only achieve the balance of heat in and out or not increase obesity. In fact, drinking sweet drinks, eating cakes and dried fruits, especially dried fruits that can extract oil and high-calorie foods, can make your hard-earned weight loss achievements go up in smoke. Therefore, in order to achieve a lasting weight loss effect, besides exercise, we should also make reasonable adjustments in diet.
