Massage, with legs up and ankles down, is mainly to promote blood circulation (especially to press peripheral blood to the heart), which is very effective. This was introduced by my classmate. Later, everyone did it together. It's spectacular ...

Jogging, shaking after running and relaxing muscles.

Leg press, slow down. Persistence will help.

The upper body is lying on the bed, and the legs are close to the wall, which is 90 degrees from the upper body. It is also useful to do it as soon as you have time.

There is also an upper body attached to the bed and legs pedaling in the air; Or lying on your side with one leg slowly circling in the air, you will also feel tired. But these two seem to be more effective for reducing thighs. . .
