But you must stretch after exercise. I advise you not to do too much arm exercise. Coordinated swimming

I have a good idea about the fat on my belly. I insist on walking briskly for an hour or five kilometers in the morning or within an hour after lunch or dinner. Must be valid. Remember to stretch after a walk. It is best to leave sooner or later. Come on, you can't go any faster. It takes at least half an hour to maintain this speed, then slow down slightly for ten minutes and accelerate for another half an hour. Hang in there ~! If you stick to it well, I estimate that it will have an effect in two weeks.
