Abstract
Abstract An improved rowing apparatus has a back bearing surface coupled to the oar arms of the apparatus to maximize the rowing exercise. The bearing surface can be fixed to a seat back of a seat movably mounted on the frame of the apparatus. The seat back can be pivotably mounted to the seat to maximize the forces of the leg, back and arm muscles in the rowing exercise.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
104 words
An improved rowing apparatus, comprising: an elongate support frame; a seat movably engaged on said frame; a pair of oar arms pivotably mounted on said frame for resistive motion in at least one direction; and means for selectively applying the muscle forces of an operator to said seat and oar arms, said means including tension means coupled between said oar arms and an operator back bearing surface, said surface bearing against the back of the operator to increase the energy which can be dissipated in the rowing exercise to substantially maximize the forces which can be applied by the leg, arm and back muscles.
Claim 2
Dependent Claim
104 words
An improved rowing apparatus, comprising: an elongate support frame; a seat movably engaged on said frame; a pair of oar arms pivotably mounted on said frame for resistive motion in at least one direction; and means for selectively applying the muscle forces of an operator to said seat and oar arms, said means including tension means coupled between said oar arms and an operator back bearing surface, said surface bearing against the back of the operator to increase the energy which can be dissipated in the rowing exercise to substantially maximize the forces which can be applied by the leg, arm and back muscles.
