Personally, I think fitness is really a good exercise for our health. Fitness can't help us lose weight, but can make us have a better figure and shape a good figure. These are the great benefits and changes that fitness has brought to our health, but we must also understand that it is too late. Fitness also depends on our usual amount of exercise and the length of exercise. If you exercise for four hours every day, unless you are a professional athlete, it will only bring harm to your health.

One; Cause physical fatigue

Above, I have mentioned a word, that is, it is too late. In fact, everything in the world is like this. Some things are good, but once they are done, they will show their disadvantages. Fitness is such a typical example. We want to change our physical quality and shape through fitness. If you go to fitness for a long time because of your physical fitness, it will damage your health. The most likely thing is physical fatigue. It is true to do a certain sport for a long time.

Second; Form sports injury

One thing we must understand is that sports injuries are likely to cause irreparable harm to our bodies. We have also seen such reports in the news that some athletes have caused sports injuries and even paralysis and amputation during training. This also shows that a lot of exercise for a long time will really damage our health. We are not professional athletes, so we must know enough is enough. Take running for example. If you run for a long time, regardless of your physical condition and weight, your knees will be irreversibly injured.

Third; Will affect our mental state.

As we all know, proper exercise can really improve our mental state, make our bodies produce an exciting substance and keep us excited. However, if we do a lot of exercise for a long time and keep exercising for four hours every day, as mentioned above, it is likely that our mental state will become sluggish and even lead to depression.
