Other stovepipe methods:
1, put your hands behind your head (from beginning to end).
2. Keep your feet apart, and the distance between your feet is shoulder width.
3. Then bend over slowly to make the whole body form at a 90-degree angle.
Remember to keep your posture at 4.90 15 seconds.
5. Hold on for 15 seconds and then get up slowly, bit by bit. The key point is: bend down slowly until the angle is 90 degrees. Always look forward, not down. The slower you bend over and get up, the better the effect. Over and over again, you will find that your thighs are very sour. Do 15 every day for a week, and it will be effective.
