Why can't I do sit-ups?

When it comes to sit-ups, everyone must be familiar with it, because elementary school students start learning how to do sit-ups, but different ages have different requirements for the standardization of movements, so many people have not really mastered how to do sit-ups. So now I still have doubts as to why I can never do sit-ups. This is actually because I have not mastered the specific method of sit-ups. So how should you do sit-ups?

Standing height

The higher you stand, the more effective sit-ups are. The correct way is to keep your body at a 45-degree angle to the ground as long as possible (at least 30 seconds) to exercise your abdominal muscles most effectively.

Principle of weight loss: When the upper body is lifted to a 45-degree angle with the ground, the abdomen is at the best time to be stressed. No matter what kind of curling exercise we do, extending the duration of the 45-degree angle between the body and the ground can make the abdominal muscles get the most effective exercise. You should know that after standing up from traditional sit-ups, you need to let your forehead touch your knees before returning to the original position. That is, the upper body quickly rises from a lying position to about 90 degrees. In fact, the burden on the rectus abdominis has not reached the heaviest stage before standing up to 45 degrees. When the angle exceeds 45-90°, the "resistance arm" from the body's center of gravity to the hip fulcrum keeps shortening, and the rectus abdominis is not under much pressure. Only when the upper body is raised to 45 degrees is the best time for the rectus abdominis to "resistance growth function".

How to determine your standing height

1. Generally speaking, when the line of sight is level with the bent knee joint, the angle between the body and the ground is 45 degrees;

2. Feel it slowly as you rise. When you feel the greatest force on your abdomen, it is a 45-degree angle. Stop at this position.

Suitable speed

Many girls believe that the faster they do sit-ups, the better the weight loss effect will be. In fact, the faster the speed, the less pressure the abdominal muscles will receive. The correct method is to slow down as much as possible and exercise the ability to control the abdominal muscles. The most correct speed should be to go up faster and go down slower.
