People sit on the sit-up fitness machine, hand holding the two pull rope hand ring, at the same time upward or to the sides to pull, to achieve the exercise of the upper body muscle groups, tighten the arm muscles.
The correct use of sit-up fitness equipment:
1, first of all, put your feet, feet should be put on top of the foam cotton. With the ground into 90 degrees, and then the body to lie back.
2, the head does not need to rely on the supine board, some people in the supine board will be the whole body lying directly on it, this method is wrong.
3, to do sit-ups, you need to lie down, the center of gravity down, hands on the ears position. Then slowly get up.
4, you should tighten the abdominal muscles and pause for a moment, and then slowly bring the body back down, when re-posted to the supine board, you can start the next cycle, sit-ups, mainly to tighten the abdomen. Instead of lifting the waist up, the practice of lifting the waist up is incorrect, it does not exercise the abdominal muscles, but only the iliopsoas muscles. Secondly, lifting the waist puts pressure on the lumbar spine, which can easily cause damage. The correct practice should be to sit up only the upper body to form an arc.
