Abstract
The invention belongs to the technical field of body building equipment, and particularly relates to an abdominal muscle training device capable of loading weight. The device comprises a front support rod, a rear support rod, a connecting rod, a stand column, a backing plate hinge rod, a sitting height hinge rod and a leg support rod, one end of the connecting rod is fixedly connected to the middle of the front support rod, the other end of the connecting rod is fixedly connected to the upper portion of the stand column, a limiting component is fixedly connected to the end face, close to the front support rod, of the connecting rod, the top of the stand column is hinged to one end of the backing plate hinge rod, a sitting plate is fixed to the upper portion of the free end of the backing plate hinge rod, a backing plate is hinged to the rear end of the sitting plate, two should straps of the same structure are detachably installed on the left edge and the right edge of the upper surface of the backing plate, at least one loading hole is formed in the position, between the two shoulder traps, of the backing plate in the extension direction of the plate, and cover plates are detachably installed at the loading holes. Accordingly, on one hand, weight loading operation is easy and safe; on the other hand, multiple dumbbell pieces can be loaded as needed, and the training requirements of most trainees can be met.
Description
technical field [0001] The invention belongs to the technical field of fitness equipment, and in particular relates to a weight-bearing abdominal muscle training device. 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 the abdominal muscles contract, they flex and rotate the trunk 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 can lead to anterior pelvic tilt and increased physiological curvature of the lumbar spine, and increase the chance of low back pain. As a way of exercising the body, sit-ups can effectively exercise the abdominal muscles and are deeply loved by people. The training method for sit-ups is: lie on your...
