An apparatus for providing suspension and resistance training is disclosed. In one embodiment, a main strap includes a fastener for engaging an anchor at an upper end and a connection point that accepts a load at a lower end. A retraction unit, which provides non-load redundancy to the main strap, includes a coupling member securing the retraction unit to the fastener. The main strap is threaded through the ring end fitting. In an extended configuration, the retractable cable is fully extended, and the length of the main strap is fully extended with the main strap having a non-load transferring relationship to the retraction unit in the extended configuration. In an unloaded retracted configuration, the retractable cable is at least partially retracted into the retraction unit and the length of the main strap is less than fully extended.
