First of all, some fitness exercises must be persisted every day to be effective, such as running every morning, such as Tai Ji Chuan for the elderly and so on. Because these exercises are not very intense, daily exercise can increase your endurance, so these exercises will not cause too much loss to your body, but will have more benefits.
And if fitness is to develop abdominal muscles, such exercise intensity needs to be exercised every other day. Because although you are exercising, this kind of exercise intensity is harmful to your health. If you exercise at this intensity every day, you may shape your body, but it is also easy to shape many problems in your body. Therefore, moderate exercise will not only affect the effect, but also give the body a time to relax and repair. Therefore, if the intensity of exercise is relatively high, it is still not recommended to do it every day. It is better to do it once every other day or three times a week.
Therefore, the exercise frequency is not generalized, it depends on your actual situation and exercise intensity. While exercising, we should also be careful not to bring too much burden to our body, otherwise the final result will often outweigh the benefits. At the same time, exercise should be a gradual process, and you can't start training in order to achieve a certain effect, which is very harmful to your health.
So in general, some exercises can be done every day, because they are not intense and bring more benefits to the body. And some exercises need to be carried out every other day, because they are stronger, so the body needs a recovery process. Therefore, it is actually possible to exercise every day and every other day, and the exercise effect will not be greatly reduced because of stopping for one day.
