1, gluteal muscle

Some modern studies show that sit-ups are only effective for abdominal muscles within 30 degrees when the body starts to lift, so the effective action is to lift only the shoulders, not the lower back; If it continues, it will change from abdominal muscle contraction to gluteal muscle contraction. This kind of muscle division makes it impossible for trainers to train isolated muscle groups with little effect.

2. Strong rectus abdominis

Strength training such as sit-ups and push-ups can't be partial weight loss. If you want to have strong rectus abdominis, you need abdominal training to remove abdominal fat, which requires reducing body fat.

Extended data

Matters needing attention in sit-ups:

1, gradually increase the number of repeated sit-ups.

For a participant who has just started to train abdominal muscles with sit-ups, the number of sit-ups should not exceed 10 repetitions (train your abdominal muscles first). After each sit-up, stand up or lie down to rest and let the abdominal muscles relax 10 minutes or more.

2. Sit-ups slowly.

Mainly for the endurance of abdominal muscles. Therefore, only by doing sit-ups slowly can we really train the endurance of abdominal muscles.
