If you want to lose weight all over or some parts that are difficult to lose weight, it is recommended to swim and play badminton. At night, your legs are straight in bed, changing 30 degrees, 60 degrees and 90 degrees. Keep it for a long time. Don't put your legs down if your stomach can't stand it. Keep doing this every night, lean your legs 90 degrees against the wall from time to time and do some sit-ups. It will be very effective to keep doing it for a month. I just exercise every day.
