The most common sit-up method is to lie on your back with your knees bent 90? Left and right, feet flat on the ground, fixed by external force, and then sit up with abdominal muscles. Next, let's explain the benefits of doing sit-ups.

Exercising abdominal muscles can make exercisers better control their body, because abdominal muscles belong to the core muscle group and play an important role in stabilizing the body. The strength of abdominal muscles has a good supporting role on the back, which enables exercisers to increase their physical strength in other aerobic sports and recreational activities.
2, sit-ups can also lose weight, but you need to do 150 times or more to burn fat, otherwise you can only exercise abdominal muscles, which is too hard and the effect is not ideal. After a long time, it will cause damage to the spine.

How to choose supine board
1, see if the supine board is easy to shake.
If the supine board starts to shake soon after being bought or used, it proves that the quality of the supine board is poor; Generally, good quality sit-ups will adopt various anti-shake designs at the joints to ensure the stability of the product in use, which not only ensures the exercise effect, but also solves consumers' concerns about safety. You can read the instructions clearly or consult some sellers in detail when buying.
2. See if the length and width of the lying board are enough.
As the most important part of the whole equipment, the length and width of the lying board directly affect the comfort and efficiency of use. If the lying board is too short, tall friends will be awkward to use or even unable to use it. If it is too narrow, it will affect the feeling during exercise. Generally, the length of a qualified lying board should not be less than 130CM, and the width should not be less than 25CM. The products with good quality will be designed to be longer and wider.
3. See whether the material of the support frame is reliable.
We know that people who lose weight are generally heavy. Therefore, the material of the support frame will directly affect the bearing capacity and durability of the sit-up board. High-quality sit-ups are generally made of high-quality thick steel, the overall weight can reach more than 8 kg, and the load-bearing capacity can reach 300 kg. The poor quality sit-ups are often made of inferior steel, which is light and cannot guarantee the bearing capacity and durability.
