The abdominal wheel is a small propeller, which can exercise muscles and joints and lose weight. The material is generally high-quality engineering plastic, with simple design, beautiful appearance, durability and convenient use. Fat used to exercise various parts of the body, such as abdomen, waist, buttocks and arms. Because the space required for exercise is simple, it is convenient for family use.

There are two kinds of supine boards.

One is a flat supine board and the other is a curved supine board. They feel different when practicing. The flat plate is suitable for most people, and the curved supine plate can relax the spine. For people with bad waist, you can also relax the muscles of the waist.

Function: Sit-ups consume abdominal fat quickly, which is also the main method to relieve lumbar muscle strain. Doing this exercise often can give you a charming waist curve.

Features: 14 exercise methods, two dynamic tension ropes and a car sponge pad. Suitable for people of different heights, light and retractable.

Sports parts: Do sit-ups to exercise six abdominal muscles, quickly consume abdominal fat, and also do push-ups, push-ups and other actions to strengthen upper limb strength.

Key points of exercise: Sit-ups are actions that many people are very familiar with. Because most people have to hook their feet to make their waist concentrate on completing the action, it is better to buy a supine board and practice at home.

Generally, the height of the supine board can be adjusted. The higher the height, the greater the strength of sit-ups. At the beginning, from the lowest, gradually increase. After a month's exercise, you can try to move up a notch. But the height cannot be too high. For ordinary bodybuilders, 40 ~ 45 degrees is enough.

When using the supine board, you need to be careful not to lie down completely, preferably 2/3, and don't lie down suddenly, but get up quickly and lie down slowly. It is wrong to put your hands on your ears and cross your head when you do the action, which will hurt your cervical spine.

Sit-ups

1, two straight pushes, sit-ups and lying flat, someone must press each other. Many people like straight legs and think it works well. Actually, it's not hot. When the leg is straight, the inner tendon will jump tightly without retreating, which makes it difficult to lift up and work. It makes people more laborious. But also neck strain.

2, the position of the hand. More than 90% will choose to cross their hands and hold their heads, so that the arms will give strength to the cervical spine and cause cervical strain.

Three, come on, lift, slam. On the one hand, speed has its own rhetoric. Fast can exercise explosive power, slow can better stimulate muscles comprehensively and evenly. For most people, the latter is better. Many times it's inertia, the effect of muscle exercise disappears, and concussion is not fun.

4. Lift the car body to 90 degrees with the ground. 90% people will choose to reach the highest point, thinking that this is a cycle. Actually, it is not. After exceeding a certain angle, the strength of muscles will drop sharply, and more is the support of rotation and bones, which greatly reduces the exercise effect.
