Abstract: A support assembly and exercise system provides safe and unconstrained movement of free weights within a movement zone encompassing normal travel of the free weights during exercise. The system allows safe user engagement and disengagement with the free weights while continually tethered against uncontrolled and possibly harmful movement. The support assembly is defined by a generally free-standing frame with rigid uprights for supporting takeoff and landing zones for the free weights, as well as tether attachments for movably supporting the free weights through the movement zone. A support member has a pivotal attachment to the upright frame for suspending the free weights against an uncontrolled release or fall. Launch and landing platforms attach to the upright frame for ideal positioning of the free weights prior to and following a usage session (workout).
