Abstract
An exercise machine having a frame supporting a seat in an off-the-floor position. A pair of arm levers are mounted on the frame and provide resistance to movement in two directions, with the resistance to pushing from rest positions being less than the resistance to pulling to return the arms to the rest positions. The machine has a pair of leg levers wherein resistance to movement in a pushing direction is greater than in a pulling direction. The resistance to movement of the exercising levers is provided by friction mechanisms and springs, with the frictional force being greater than the spring force. The friction mechanisms offer the same resistance in either direction of movement, but the springs aid movement of the arm levers in push, when returning them to rest positions, while aiding the foot levers in a pulling direction. The arm levers have grips rearwardly inclined from the main portions thereof for better in-line application of force by the user. The seat is rearwardly tilted to a position where hyperextension of the legs is prevented. The seat can also be adjusted fore and aft to accommodate variation in user size.
