An apparatus includes adjustable resistance exercise assisting devices, including a hand grip and a bar grip, each having a length of cable wound about and fixed at one end to a cable spool and an opposite end with a quick connect fitting for removable attachment to an anchor point, whereupon forced movement of the exercise assisting device away from the anchor point, by pulling, pressing or pushing in the performance of various exercise movements, causes the cable spool to rotate against resistance imparted by a resistance adjustment mechanism. In one embodiment, the resistance adjusting mechanism includes a piston that moves against pressure within a variable volume airtight chamber as the cable spool rotates. The apparatus may also include a rigid garment that is worn about the human torso and which includes multiple anchor points for attachment of the cable quick connect fitting thereto.
