Lagu's fitness assistant has his own college dog, and this fitness software is used in school. There are many basic videos in it, which are very practical. But personally, I think it's better to buy a dumbbell or something, because there is no fitness equipment, so I can only do push-ups, running and sit-ups, and the exercise effect is not very good. In addition, exercise emphasizes three-point exercise and seven-point diet. Learn more when you eat, and the effect will be better.
