Linear movement, trunk muscle exercise method |
摘要 |
An exercise method for strengthening the lower back muscles has a horizontally-movable plunger that contacts the abdomen of a user for linearly applying the force of a weight stack to resist lower back and pelvic muscle flexion and extension by a seated user. The plunger is attached to a carriage mounted for horizontal movement on rails. A cable connection between the carriage and the weight stack includes a cam for varying resistance with changes in position of the plunger. The backrest and seat are made optionally tiltable.
