How long should you exercise your muscles?

If you want to have healthy and strong muscles, you can't do without persistent exercise, but is the longer the exercise time, the better? The answer is of course no. Muscles will also get tired, so a combination of work and rest is good for muscle plasticity and fatigue recovery. So how long is the appropriate time for muscle exercise? Muscle exercise should be carried out at least twice a week. If you don't exercise for more than three days, it will not do your muscles any good, and the previous exercise effects will disappear.

Rest is necessary when doing muscle training, but the time should not be too long. Muscle training consumes a lot of nutrients. After exercise, after proper rest, the nutrients in the muscles are quickly replenished, and the amount replenished will be more than what is consumed. This phenomenon is called "super recovery" in physiology. "Super recovery" allows muscles to obtain more nutrients, making them more developed with more training. If muscles are not given sufficient time to replenish nutrients, they will not grow stronger than before. Some studies have shown that this rest period is calculated based on the time it takes for the muscles to regain their last exercise capacity, which generally takes 2-3 days.

After 2-3 days, if there is no exercise stimulation, the exercise effects of the previous period will gradually fade away. This is because muscles are also composed of various proteins, and proteins, the substances that make up muscle, are in a dynamic state of constant consumption and replenishment. If you replenish more, your muscles will grow; if you consume more, your muscles will decline.

The above content is about how long it is appropriate to exercise your muscles. It can be seen that after each exercise, the rest time should not exceed three days, that is, you should exercise at least twice a week, but exercising every day is not good. This is because excessive muscle exercise will produce lactic acid, which is a toxic substance and is not good for your health over time.
