Abstract: An adjustable resistance exerciser for gymnasts is provided in a vertical frame attached to a squared base platform. A horizontal pivotable handlebar is affixed at the ends to length adjustable side arms which are in turn attached by reversed sprag clutches to individual disc brakes. The disc brakes are supported by box shaped carriages arranged to be moved vertically up and down in paralleling track-like side members which make up the vertical frame. Opposite torque can be applied to either arm by manually adjusting the braking. The side arm length adjustments and the up and down carriage adjustment can be locked into selected positions which allows the device to be sized for a variety of users.
