ABSTRACT:
An exercise machine includes left and right adjustable resistance exercise mechanisms operated by hand levers linked to pivotal pedals. The machine is positioned before a user seated on a stationary support. To facilitate movement of the machine by a seated user who may be elderly or infirm, a retractable front caster wheel is deployed, elevating the machine off its support posts and onto the front caster wheel and two rear wheels. To stabilize the operating machine against movement when a high resistance is used, retraction of the front caster wheel lowers the machine onto front and rear support posts. Further stability is provided by an anchoring channel which receives the front legs of the user support. A cord attached to front end of the machine connects to the channel and applies tension to anchor the machine against movement. The hand levers are provided with a locking pivotal adjustment to permit the hand grips to be positioned comfortably for the seated user.
