Abstract

The invention relates to a comprehensive abdominal muscle training device and belongs to indoor fitness equipment. A backup plate connected with a spring is arranged on one side of a sit-up plate, the backup plate is detachably arranged on support bars rotationally connected with two sides of the sit-up plate, the spring provides certain elastic force for the backup plate, a weak exerciser can be assisted in finishing exercise actions, and the load of the exerciser can be increased and the exercise efficiency can be improved by changing the compression state of the spring into the tension state and fixing the chest of the exerciser with the backup plate; a loading mechanism is arranged on the other side, legs or feet of the exerciser can stretch below a padding belt when the exerciser performs the crunch, a certain role in fixing the legs of the exerciser can be played, a connecting pin can be combined with different load bearing blocks as required to provide different degrees of extra loading force, and the exercise effect can be improved.

Description

technical field [0001] The invention belongs to fitness equipment in the field of sports equipment, in particular to a comprehensive training device for abdominal muscles. Background technique [0002] The abdominal muscles are an important part of the connective tissue in the human body, including the rectus abdominis, external obliques, internal obliques and transverse abdominis. When contracted, they allow the trunk to flex and rotate and prevent the pelvis from tilting forward. The abdominal muscles also play a very important role in the activity and stability of the lumbar spine, and can also control the activities of the pelvis and spine. Weak abdominal muscles may lead to anterior pelvic tilt and increased physiological curvature of the lumbar spine, and increase the risk of low back pain. Having perfect abdominal muscles can enhance personal charm and self-confidence. [0003] In real life, abdominal muscles are usually exercised through exercises such as sit-ups o...
