According to the national students' physical health standards, college girls passed 27 sit-ups. Practice sit-ups, the speed varies from person to person. You can try to do it five times a minute at first, and then slowly increase it until it reaches about 50 times.

For women under the age of 30, the frequency should be controlled at 60 ~ 70 beats per minute, which decreases with age. For women over the age of 50, 25 beats per minute is enough. For people who have a certain fitness foundation, they want to strengthen their abdominal strength through practice and ensure that they do it about 60 times a minute.

Matters needing attention in sit-ups:

It is necessary to gradually increase the number of sit-ups

Many people think that the more sit-ups, the better the fitness effect. In fact, this is wrong. Doing sit-ups for a long time will do harm to the spine. For a participant who just started to train abdominal muscles with sit-ups, the number of sit-ups should not exceed 10 repetitions each time. And stand up or lie down to relax the abdominal muscles 10 minutes or more after each finish.

The act of sit-ups

Many people think sit-ups are very simple, that is, lying down and then lying down. It's not as simple as it looks. Doing sit-ups in the sagittal plane will obviously limit the training effect of the external oblique muscle and the internal oblique muscle. Only by increasing the rotation of the longitudinal axis of the body (from the right shoulder to the left leg and from the left shoulder to the right leg) can abdominal muscle training's uncoordinated state be avoided.
