For normal people, going three times a week can have the effect of fitness, and taking a day off after exercise is helpful for muscle recovery, ensuring that the body will not be overtrained and will not affect normal work.

For a professional fitness instructor, it takes at least five times. Because the fitness instructor has a good physical quality, training for five times can make the body more perfect. And correspondingly, the fitness instructor will also take some supplements to increase the body's recovery ability and muscle synthesis ability.

Therefore, based on the above factors, it is better for normal people to exercise three times, and it is better for fitness coaches to exercise five times.
