Abstract: A door mount system for securing exercise devices to a door for use by a user. The door mount system includes a support member, a securing member, an attachment member, and an adjustment member. The adjustment member is adapted to move the securing member. A securing member is adapted to press on the door to removably connect the support member to the door. The attachment member is adapted to connect to an exercise device. The door mount system may further include guide members and slots. The guide members slidably move in the slots to prevent rotation of the securing member. The attachment member may include one or more eyelets adapted to connect to the exercise device.

Abstract: An exercise machine with multiple platforms for an exerciser to perform a variety of exercises generally includes an elongated frame structure supporting stationary first and second end platforms, a longitudinal rail extending between the end platforms and having an upper surface comprising a central platform, and a slideable carriage platform that reciprocates on the rail over the central platform and between the end platforms. The platforms provide multiple support surfaces at multiple elevations on which exercisers can position parts of their bodies during exercise. The platforms may be provided with positioning indices and provide continuous support surfaces over substantially the entire length of the exercise machine. The central platform may be provided with finger grips for exercisers to grasp. One or more mounting platforms may be provided to facilitate mounting and dismounting of the exercise machine.
