About running in situ

The most effective way to reduce thighs is to climb stairs, lasting more than 40 minutes each time, not less than 4 times a week, and you should be able to lose weight in 20 days. However, I still suggest that you don't set the time so dead, because the effect of losing weight varies with your physical fitness. In addition, no matter what exercise you do, paying attention to stretching after exercise will not lead to muscle agglomeration.
