I think this is divided. When I first came into contact with fitness, the first day of fitness, because of physical discomfort. After a day's exercise, the muscle pain in the exercise area can basically last 1-2 days. During this time, repeated exercise will not only lose weight, but also lead to injuries due to poor muscle control. Therefore, I think when we are newcomers, we still need to rest for a day or two after each fitness.
Another reason is that people who have just started to exercise will be too tired and tired of fitness if they go to fitness every day. At this time, it is best to step by step. It is best to exercise the next day.
There are also people who have always had fitness habits, and their bodies have become accustomed to this strenuous exercise. I think I can exercise every day, but it's best to take a day or two off every week, and use this time to completely relax the muscles exercised this week, so as to meet next week's work or fitness plan in a better state.
The goal of our fitness is still to be healthy, not to rank like those fitness athletes. So we don't have to go to the gym every day, and we don't always receive high-intensity training. At the same time, we also need a proper rest to let our muscles usher in a new fitness.
Of course, the most important thing is, whether you exercise every day or every other day, you must stick to it next time, so that the fitness goal can be achieved. So stick to it.
