Exercise apparatus

An exercise apparatus comprising:

• a frame;
• at least one elongated sheet of flexible material having a first end coupled to the frame and having a second free end positioned frontwardly relative to the frame, the sheet of flexible material having an upwardly facing support surface, and the sheet of flexible material having a predetermined stiffness for supporting substantially the entire weight of an exerciser of the apparatus;
• and
• at least one support assembly mounted to an upper portion of the frame and generally overhanging the support surface of the sheet of flexible material for further supporting the exerciser upon pushing downwardly against the sheet of flexible material and thereby moving the second free end of the sheet of flexible material downwardly, and for supporting the exerciser upon pulling upwardly away from the sheet of flexible material to release the downward force against the sheet of flexible material and thereby permitting the second free end of the sheet of flexible material to move upwardly.
