In fact, there are many ways to exercise, but the best way is to find the one that suits you.

At that time, it may be more difficult for you to keep healthy. The best way is to follow the arrangement of the fitness coach, or find a suitable fitness method and exercise with the video, which means that he can do this, but whether you can do this or not requires some self-evaluation.
