Exercising apparatus includes a collapsible frame having upper and lower tracks supporting upper and lower groups of pulleys and moveable upright track supporting risers. The upper pulleys support an adjustable friction block partner supporting harness adjacent the frames front end, and a line extending from the friction block over upper pulleys to a coupling transmits a friction block enhanced force related to the partners weight. A multiple path pulley arrangement joined to the coupling provides a mechanical advantage, reducing by a multiple the effective force delivered adjacent the frame\s back end to an exercising bar spaced apart from the exercising partner through lower track coupled pulley blocks. A separate line from the upper track passing through an offset pulley, is extendable to the lower lines to allow for pull down exercises. In use, a partner sits on the harness transmitting a force to the adjustable friction block which is enhanced and transmitted though the multiple pulley paths, thereby reducing the effective resistive force. That force is transmitted to exercising bars lifted or pulled by the exercising individual.

A two person cooperative exercising device for use by an exercising individual and a partner comprising: exercising means for transmitting a resistive force for exercising to an exercising individual; means for supporting a partner and providing a force related to the gravitational weight of the partner, the partner supporting means spaced apart from the exercising means; a pulley arrangement including line means for transmitting the partner related force of the exercising partner from the partner support means to the excercising means, the pulley arrangement coupled to the exercise means; upper support means for supporting the pulley arrangement to movably support the partner supporting means; lower support means for supporting the pulley arrangement to receive the partner related force for the exercising means; means for retaining the upper support means in fixed relationship to the lower support means; and means for adjusting the partner related gravity force, the adjusting means coupled to the pulley arrangement, said pulley arrangement being adjustable by the partner at one station and the partner\s related gravity force being transmittable to the exercising means at another station whereby the partner may supply and adjust the significant portion of the force transmitted to the exercising individual, thus providing a two person cooperative participation apparatus for an exercising program.
