Use of sit-ups fitness equipment
1 First of all, pay attention to the position of your hands when using them. The correct posture is that your hands are slightly attached to your ears, and your hands can be crossed on your abdomen for the first contact, which reduces the difficulty. When sitting up, let your abdomen exert strength instead of raising your head with your hands as usual.
2. Then, when you sit up, you should rely on your abdomen to make a correct posture. When you get up, the abdominal muscles will pull you up, keep your back slightly bent, and don't straighten it, otherwise it will easily cause back muscle strain.
3, the height of getting up is also standard. In the process of 45-90, due to the continuous shortening of the resistance arm from the center of gravity of the upper body to the fulcrum of the hip, the burden of the abdominal muscles that play the role of cranes is getting smaller and smaller, and the burden of the rectus abdominis is not the heaviest. The best time for the resistance growth function of rectus abdominis muscle is only when the upper body reaches 45. So sit-ups are not as effective as the height of getting up. The correct posture should stop at the position of getting up about 45, and then slowly return to this position, so that the abdominal muscles can be fully exercised.
When you do sit-ups with many people, you will get up quickly. But in fact, the faster the speed, the less pressure on the abdominal muscles. The correct way is to slow down as much as possible and exercise the control ability of abdominal muscles. You will find that when you do it in slow motion, there will be a burning sensation in your abdomen, that is, fat is burning. Take a deep breath when you lie down, and exhale slowly when you get up to control the rhythm.
Sit-ups are a particularly good exercise for abdominal muscles. In particular, some friends who want to thin their stomachs or practice abdominal muscles can often do sit-ups. If you want to use equipment to complete it, you need to master some key points. Put your hands in the right place. Get up on your abdomen, not too fast.
