1. Stand up straight with your feet slightly wider than your hips and your knees slightly bent. Keep your eyes straight ahead and your back straight. Take a two-pound ball or other object with the same weight in both hands and put it on your hips.

2. Hold the ball in your right hand, straighten your arm and pass the ball to your left hand at the top of your head.

3. Put down your arms, return to your hips, and start passing up and down again. The movement of arms looks like a spinning windmill.

4. Repeat the passing action 20 times. Move slowly, not by impulse.

Note: Don't pass the ball by moving your wrist. Keep your arms, back and neck straight so that you can pass the ball naturally instead of rolling it.

Don't try drugs, those things are definitely harmful to health. If you are determined to lose weight, you should start from all aspects of yourself and develop good eating and living habits. That's the best way to lose weight.
