1. Pedal 100 times before going to bed every day. Have a fixed rhythm. Don't rush or slow down. Just pedal at a medium speed. Don't think about anything else, so you won't feel tired.

2. Don't put it down immediately after kicking, keep a prepared posture, put your legs together and straighten up into the air. Don't bend your knees, keep your toes straight. Hold on for 3 minutes, and then slowly put it down.

3. After the above actions, the whole leg will be a little sore. Remember to massage the leg well.

4, this action may be hard, if you don't adapt, you can do it 50 times at a time. It should be noted that this action must be persisted every day and can't be stopped for a day, which has no effect at all! If there is, it should be regarded as a fixed class every day.
