Description

[0001] The utility model relates to a power-assisted supine board, belonging to the technical field of supine boards. Background Art

[0002] The supine plank is a popular home fitness device primarily used for abdominal exercises like sit-ups. While it offers convenience for toning abdominal muscles, it also has some potential drawbacks and limitations:

[0003] 1. Risk of spinal injury: Traditional sit-ups, if performed incorrectly, can engage the gluteal and abdominal muscles, leading to spinal damage. This is especially true for those with weak abdominal muscles or those who exercise regularly. Improper form can cause compression of the lumbar intervertebral discs.

[0004] 2. Excessive involvement of the gluteal muscles: During sit-ups, if you continue to stand up beyond a certain angle, the contraction of the abdominal muscles will turn into contraction of the gluteal muscles, which may reduce the effect of abdominal muscle training.

[0005] 3. Incorrect movement techniques: Many people do not perform sit-ups in a standard manner, such as holding their heads with both hands, standing up too quickly, etc. This not only affects the exercise effect, but may also increase the risk of injury. Utility Model Content
