1 How to kick in bed When we lie down, our legs are lifted up together to form 45 degrees or 60 degrees with the ground. At this time, our legs began to kick in the air, just like riding a bike on the flat ground. This action is not difficult, but we'd better have a bigger arc when kicking, so that the effect will be more obvious. Complete three groups at a time, each group doing 30 actions.

When the stovepipe kicks short, we mainly rely on our legs to complete the action. Our legs need to be lifted up and kept pedaling in the air, just like we pedaled in real life. So this action can effectively exercise our leg muscles. When we finish 100 air kicks, we can obviously feel the leg muscles sour, which shows that it has played an exercise effect.

3 Exercise abdominal muscles Kicking in the air can also effectively exercise our abdominal muscles, because when our legs are lifted up, our abdomen is sinking and in a tight state, and our abdomen should support our legs to complete the action. So it can also play an auxiliary exercise effect on the abdomen. Although the abdomen has never been exercised, it can also be exercised effectively, and the greater the leg strength, the deeper the abdomen tightening, and the better the exercise effect.

4 Tightening the buttocks is mainly because the buttocks are close to the position of our thighs. When our legs are lifted, our hips are tightened forward. Therefore, when our legs are exercising, our hips are actually following the exercise, which can play a sports effect and make our hip muscles more compact. However, we need to keep exercising every day and spend more time.
