This movement is too big and will hurt the foundation.

Many people make the mistake of doing sit-ups too quickly, but this is inefficient because it uses the hip muscles most instead of the abdominal muscles. Not only that, but your hips transfer stress to your back, which can cause you discomfort during or after a workout.

Sit-ups are considered the most classic traditional method of waist and abdomen training. The muscles that can be trained include the oblique abdominal muscles, transverse abdominal muscles and rectus abdominis. However, if sit-ups are performed incorrectly, the exerciser is likely to experience pain in the lower back muscles. Fitness expert Wood points out that the best type of sit-ups is the type that works your abdominal muscles without causing back discomfort.

There is a speed requirement for doing sit-ups. Doing sit-ups too fast can cause serious harm.

Many people make the mistake of doing sit-ups too quickly, but this is inefficient because it uses the hip muscles most instead of the abdominal muscles. Not only that, but your hips transfer stress to your back, which can cause you discomfort during or after a workout.

Experts remind that sit-ups should be done slowly, concentrating on controlling every detail of the movement. The pelvis and ribs should move at the same time, and the neck and shoulders should be kept relaxed to avoid excessive tension in the upper body and strain.

Sit-ups should be done "completely"

Doing a full sit-up on the ground is more effective than using a stability ball and only doing a partial sit-up. Research conducted by the University of Georgia Medicine in the United States found that unassisted sit-ups can exercise the abdomen, back, shoulders, hips and legs, while doing sit-ups on a stability ball is the least effective way.

However, if you want to work your upper body core muscles and protect your back from pain, you can use a stability ball to help you work your buttocks, hips, and lower back. When doing sit-ups with a stability ball, keep your feet planted on the ground, press your back against the ball, find your balance, and then do a normal sit-up.

Where should you place your feet during sit-ups?

According to the famous Mayo Center in the United States, using an object to fix the feet while doing sit-ups can help exercisers to exercise the abdominal muscles alone, thereby improving efficiency. The correct way is to place your feet loosely under the edge of a heavy object such as a bed or table, rather than letting others press on your feet, as this will make it easier for you to use your hip and buttocks muscles during exercise.
