  • Cross-country skiing simulator
    Patent number: 4867443
    Abstract: An exercise machine for simulating cross-country skiing is disclosed in which the poling action of the arms and the leg action both drive the same flywheel through a system of overrunning clutches. This provides a more realistic simulation of cross-country skiing than the prior art devices in which the arm motion was independent of the leg action.
