System and method for exercising

An exercise device, comprising:

• a support structure;
• a body supporting member that is selectively movable relative to the support structure;
• and
• a track linked to the support structure and the body supporting member, the track having an axis of rotation between a first end and a second end of the track along a longitudinal length of the track about which the track is configured to selectively rotate;
• the track having at least first and second configurations in which:
• in the first configuration, the body supporting member is selectively movable relative to the support structure and the track;
• and
• in the second configuration, the body supporting member is selectively movable relative to the support structure while remaining at a substantially constant position relative to said track.

An exercise device, comprising:

• a support structure;
• a track secured to the support structure;
• and
• means for selectively moving the track relative to the support structure about an axis of rotation that is between a first end and a second end of the track along a longitudinal length of the track.
