Leg training needs persistence, and time can be certified. As long as the posture is correct, stovepipe burning calories is effective. You can usually lie down, put your arms on your sides, and lift your feet up 90 degrees to strengthen the softness of your legs and eliminate the fat in your legs in time. You can also lean against the indoor wall.

If you can't reach the angle, keep practicing for an hour every day, and I believe it will be effective after one month.
