A doorway exerciser comprising a scissor-type springbiased clamp for securing the exerciser above the upper doorframe and a strap adjustable in length removably secured to the clamp and extending downwardly. The strap passes downwardly into a tube having a compression spring therein, through a slotted plate at the bottom of the spring, and returns upwardly and is secured to itself. The tube is preferably of plastic and has opposed ears extending therefrom with a slotted orifice in each ear. A loop at one end of each of two flexible straps passes through each orifice. The other ends of the straps are removably secured to the ends of slats which support a fabric seat.
