ABSTRACT:
An exercise machine making use of the body weight of an exerciser as a load weight thereof comprises a base, a fixation rod member, an upper rocking bar member, a lower rocking bar member, an expandable connection bar member, a seat pad, a back pad, a handle, and a cushioning member. Unlike a conventional exercise machine, the exercise machine so disclosed is composed of no weights. The fixation rod member can be adjusted in accordance with the height of an exerciser. The length of the expandable connection rod member can be adjusted by adjusting the pivoting position of the upper rocking bar member or the length of the fixation rod member. The exerciser can use the machine by seating or standing on the seat pad of the machine for doing the muscle-building exercise.
