This is good for each of us, after all, each of us will get old one day. The health of the elderly is very important, because the elderly often have various diseases, which are caused by overwork and unhealthy living habits when they are young. These diseases will hide when we are young, and then break out together when we are old, which makes us miserable. Therefore, both young and old people should take some time to exercise. If they can pay attention to exercise when they are young, their mental state will be much better than their peers when they are old.
Older people should also pay attention to gradual exercise, and don't do particularly difficult fitness exercises as soon as they start, which will make the body unbearable. After all, an old man can have a big accident when he falls. And being too tired is not exercise for your health, but torture. So I think this gym 1.5 hours is reasonable and suitable for the elderly. When using the treadmill, we can use the slowest speed first, get used to it and then gradually speed up. But I don't recommend the elderly to run often, because it will hurt their knees and their physical strength will not keep up.
And if the elderly with their own diseases should be cautious about fitness, I think the gym should be more afraid of accepting the elderly with heart disease or other diseases. After all, if something happens to the elderly in the gym, the family members will definitely come to claim compensation, and the whole gym may be lost. Therefore, I suggest that elderly people with physical diseases take a walk around their own community, which can also achieve the purpose of exercising. In fact, as long as you stay happy, diseases will not be so easy to find you.
