Personally, I think Duoyan Zheng's aerobics is very good and effective. At the beginning, the movements will be a little nonstandard, and you will feel muscle aches after finishing. However, if you do it more than three times, the problem will not exist. At first, you can do it once a day and do aerobic exercise for about 30 minutes. Exercise before you do it, do it three times a week for about half a month. However, you must insist that it is obvious to lose weight in 2-3 months. The main exercise is not just my own doing. I must have a full breakfast, subcontract lunch at 8 o'clock, eat less at dinner and eat fruit before meals. It takes about an hour and a half to do aerobic exercise after dinner. I hope it helps you.
