If it is high-intensity exercise, like anaerobic exercise with equipment, it will hurt joints and ligaments every day. Generally speaking, the most reasonable high-intensity exercise for fitness people is once every 2-3 days, because muscle recovery takes 48 or 36 hours.
If it is moderate exercise, such as aerobic jogging, it is usually best to do exercise once every two days, because aerobic exercise will last for two days.
If it is low-intensity exercise, such as striding for 20-30 minutes and doing it once a day, it is very beneficial to the body. Therefore, it is necessary to arrange the exercise time reasonably. Blind overload exercise is not only harmful to the body, but even harmful to the body.
Most healthy people should do at least 30 minutes of moderate-intensity exercise at a time, such as brisk walking, five times a week, plus 10 to 15 minutes of high-intensity training, two or three times a week. These exercises can help reduce the risk of hypertension, stroke, coronary artery disease, type II diabetes, colon cancer and osteoporosis, and help prevent the natural loss of muscle groups, which can slow down metabolism and make the body gain weight in its thirties, forties or fifties.
If you want to lose weight, you need to do more activities. It is best to do an hour or 90 minutes of moderate-intensity exercise, or half an hour of strenuous exercise, such as jogging, strenuous aerobic exercise or fast-paced cycling. Of course, no matter what exercise you do, it's better than nothing. Persistence will be effective. It is much better to do 30 minutes of moderate exercise or 10 minutes of strenuous exercise every day for a week than the "weekend warrior" type of excessive exercise twice a week.
