The simplest and most effective way is to lie flat on the bed every night before going to bed and lift your legs for 15 minutes of empty riding. Stick to it for a long time, and you will find unexpected surprises. This action is helpful for the abdomen, thighs and calves, but the action should be standardized and 90 degrees. Long-term persistence will have an effect, don't worry about belly meat.
Lie on your back in bed with your legs imitating the riding posture, and do it for 20 minutes every night before going to bed. 1~2 months is effective, but pay attention to fasting for 3 hours before going to bed, mainly thighs and buttocks.
