The present exercise machine includes a frame, a seat, foot pedals, a resistance device and a hand crank assembly. The resistance device includes a rotating element such as a cylindrical fan which would require a power input in order to continue rotating. The hand crank assembly is pivotably mounted to the frame such that the hand crank assembly can quickly pivot between a first position suitable for a seated operator and a second position suitable for an upright operator.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is: 1. An exercise machine comprising: a frame, a seat for supporting an operator, a pair of opposed foot pedals, a hand crank assembly including hand cranks and a resistance device mounted to said frame, said foot pedals, said band crank assembly and said resistance device operatively interconnected by a drive train, said hand crank assembly pivotably mounted to said frame for pivoting between a first lower position and a second raised position, the first lower position characterized by placement of said hand crank assembly in a generally horizontal position such that said hand crank assembly is directed toward said seat and such that said hand cranks are relatively lower and closer to said seat whereby a seated operator may more easily grasp said hand cranks, the second raised position characterized by placement of said hand crank assembly in an orientation directed away from said seat such that said hand cranks are higher than when in the first position and more distant from said seat than when in the first position whereby said hand cranks are in a position suitable for grasping by a standing operator, whereby an operator may pivot said hand crank assembly between the first lower position and the second raised position when changing between a seated position and a standing position, and, said hand crank assembly is operatively associated with said resistance device such that greater resistance is provided to the hand cranks when the hand crank assembly is in the second raised position and less resistance is provided to the hand cranks when the hand crank assembly is in the first lower position. 2. The exercise machine of claim 1 wherein: the resistance device is a fan. 3. The exercise machine of claim 1 wherein: the resistance device is a fan, and air flow through the fan is regulated by a hamper which can move between a relatively open position and a relatively closed position. 4. An exercise machine comprising: a frame, a seat for supporting an operator, a pair of opposed foot pedals, a hand crank assembly including hand cranks and a resistance device mounted to said frame, said foot pedals, said hand crank assembly and said resistance device operatively interconnected by a drive train, said hand crank assembly pivotably mounted to said frame for pivoting between a first lower position and a second raised position, the first lower position characterized by placement of said hand crank assembly in a generally horizontal position such that said hand crank assembly is directed toward said seat such that said hand cranks are relatively lower and closer to said seat whereby a seated operator may more easily grasp said hand cranks, the second raised position characterized by placement of said hand crank assembly in an orientation directed away from said seat such that said hand cranks are higher than when in the first lower position and more distant from said seat than when in the first lower position whereby said hand crank is in a position suitable for grasping by a standing operator, whereby an operator may pivot said hand crank assembly between the first lower position and the second raised position and when changing between a seated position and a standing position, said resistance device is a fan, and air flow through the fan is regulated by a hamper which can move between a relatively open position and a relatively closed position, said hand crank assembly is operatively associated with said fan such that said hamper moves between said relatively open position and said relatively closed position when said hand crank moves between said first lower position and said second raised position. 5. The exercise machine of claim 4 wherein: said hand crank assembly is operatively associated with said fan such that said hamper is in said relatively open position when said hand crank is in the second raised position and such that said hamper is in said relatively closed position when said hand crank is in the first lower position. 6. An exercise machine for simultaneously or separately exercising the muscles associated with moving the legs and the arms of an operator, comprising: (a) a frame, (b) a fan mounted to the frame that includes an air filter for filtering air passing through said fan and a hamper for regulating air flow through said fan that moves between a relatively open position and a relatively closed position, (c) a pair of opposed foul pedals mounted to the frame for rotation relative to the frame, (d) a seat mounted to the frame positioned such that an operator sitting on the seat may power the foot pedals with his or her feet, (e) a hand crank assembly having a distal end and a proximate end and opposed hand cranks mounted to the distal end, said hand crank assembly pivotably mounted to said frame at its proximate end for pivoting between a first lower position and a second raised position, the first lower position characterized by placement of said hand crank assembly in a generally horizontal position such that said hand crank assembly is directed toward said seat such that said hand cranks are relatively lower and closer to said seat whereby a seated operator may more easily grasp the hand cranks, the second raised position characterized by placement of said hand crank assembly in an orientation directed away from said seat such that said hand crank is higher than when in the first position and more distant from said seat than when in the first position whereby said hand cranks are in a position suitable for grasping by a standing operator, whereby an operator may pivot said hand crank assembly between the first lower position and the second raised position when changing between a seated position and a standing position, said hand crank assembly operatively associated with said fan such that said hamper moves between said relatively open position and said relatively closed position when said hand crank assembly moves between said first lower position and said second raised position, (f) a drive train interconnecting the foot pedal assembly, the hand crank assembly and the fan so that the foot pedals and the hand cranks may turn in the same direction, at substantially the same rate and so that the operator can turn the rotating element of the resistance device by turning the foot pedals or by turning the hand cranks or by turning both the foot pedals and the hand cranks, whereby all of the muscles associated with movement of the legs and arms may be simultaneously exercised from either a seated position or a standing position. 7. The exercise machine of claim 6 wherein: said hand crank assembly is operatively associated with said fan such that said hamper is in said relatively open position when said hand crank is in the second raised position and such that said hamper is in said relatively closed position when said hand crank is in the first lower position.
