Lie on the bed, keep your feet together and straighten, use the strength of your ankles to stretch the tip of the right angle and try to withdraw it, and so on.

If you have time, you can also do a simple massage

Pour the moisturizing cream (generally enough, if the slimming effect is better) on your hands, rub it hard for 50 times to warm it, and rub it from your feet to your knees (be sure to rub it backwards, because the lymphatic system that consumes fat is in the upper body), and massage.

If you persist in this, it will definitely have an effect.

This is what our aerobics teacher taught us, and the effect is not bad
