发明名称 Exercise system, apparatus and method
摘要 An exercise frame includes an upstanding back rest and an intersecting seat, with a pair of exercise arm assemblies supported along corresponding sides of the back rest and exercise leg assemblies supported along corresponding sides of the seat. Each arm and leg assembly is segmented and linked together so as to limit and restrict movement of the distal ends of each arm or leg assembly along a straight line passing through the corresponding proximal and distal ends.
