The purpose of sit-ups is to exercise abdominal muscles, but the effect of exercise is quite different because of different power points. But the main points are the same-slow and efficient.

If the landlord wants to do the opposite, he might as well try the following scheme:

According to my experience in physical examination, this movement principle is definitely 100000. . . Originality, plagiarism and reprinting are shameful! ~

1。 Preparation posture: cross your hands, hold them tightly with the back of your head and neck, put your elbows together and curl your legs. Lie flat on a special cushion, relax and take three deep breaths.

2。 At the beginning, pull the head and neck forward and upward with both arms (to preserve the strength of abdominal muscles and improve the speed), and at the same time quickly contract the waist until the elbow touches the knee.

3。 Push your knees with your elbows, and bounce your body onto the mat with rebound force.

4。 After the body touches the cushion, get up again by the reaction of downward thrust, and then repeat the series of actions just mentioned.

The purpose of this set of movements is to use the strength of various parts of the body in a short time, and at the same time, add the strength brought by the rebound to shorten the time of a sit-up. The most important thing is to save effort ~

The main points are here. I hope the landlord can understand the nuances of each part and practice hard (since the exam is coming the day after tomorrow, it is not necessary to do too much in these two days, it is important to understand its essence ~), and 50 push-ups can be easily done! ~ I wish the landlord success in the exam! ~

Please feel free to answer any technical questions.

Satisfied, don't forget to reward ~
