Claim:
An exercise device, comprising: (a) a frame, including, (i) a pair of spaced apart arcuate rails, each arcuate rail having a central curved portion, a first end, and a second end, (ii) a first end member interconnecting the first ends of the arcuate rails of the frame, and (iii) a second end member interconnecting the second ends of the arcuate rails of the frame; and (b) a platform configured to receive and support a person on the exercise device, the platform extending between and connected to the first and second ends of the pair of arcuate rails; (c) wherein, (i) the central curved portions of the pair of arcuate rails of the frame protract from a first support surface of the platform such that the central curved portions of the pair of arcuate rails of the frame are configured to support the platform on a floor in a configuration in which the exercise device is prone to end-to-end rocking motion of the exercise device relative to the floor between the first and second end members of the frame when a person is received and supported on the first support surface of the platform, (ii) the first and second end members of the frame protract from a second support surface of the platform such that the first and second end members of the frame are configured to support the platform on the floor in a configuration in which the exercise device is not prone to rocking motion relative to the floor when a person is received and supported on the second support surface of the platform, the first and second support surfaces being on opposite sides of the platform, and (iii) the first and second end members comprise a pair of hooks, each hook configured to releasably receive a resistance band.
