Abstract: An exercise device is disclosed. The exercise device includes a track having at least two parallel rails. The exercise device further includes first and second padded sleds, each padded sled having rollers attached to an underside of a base, the rollers being adapted to engage and roll along two of the at least two parallel rails. Each padded sled further includes a brake for applying a braking force against at least one of the at least two parallel rails to inhibit movement of the first padded sled, or to lock the associated padded sled into a location along the track. The exercise device can also include a static pad configured for immovable placement on the track.
