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;

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, taller friends will feel uncomfortable or even unable to use it. If it is too narrow, it will affect the feeling during exercise. Generally, a qualified lying board should not be less than 130CM and its width should not be less than 25CM, so more products with good quality can be designed.

See if the material of the support frame is reliable: We know that people who lose weight are generally heavier, so the material of the support frame will directly affect the load-bearing capacity and durability of the sit-up board. Good 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, while poor quality sit-ups are often made of inferior steel, which is light to pick up and cannot guarantee load-bearing and durability.
