Date Nov. 20, 1986.A chair which is convertible to an exercise machine comprises a front L-shaped frame member (51) and a substantially straight rear frame member (52) which is pivotable between a vertical position to form a chair and a horizontal position to form an exercise machine. In the configuration as an exercise machine, the seat (90), which has wheels underneath, slides along the rear frame member (52) as the user pulls on a bar (80) against the force of springs (85, 86). Cross-members (66, 67) serve as foot rests. The bar may be replaced by two spring members (40, FIG. 3) attached to the top of the vertical limbs of the front frame member.
