ABSTRACT:
An exercise machine of the present invention is transformable between a first mode for simulating an activity such as skiing or rowing involving reciprocating linear motion and a second mode for simulating a cycling activity. The exercise machine comprises a frame, a shaft operatively connected to the frame for rotation about a shaft axis, a flywheel secured to the shaft and rotatable therewith, and a runner. A drive roller is operatively connected to the frame and is engageable with the runner such that forward or rearward movement of the runner causes the drive roller to rotate. A one-way clutch operatively connects the drive roller to the shaft so that the drive roller when rotated in a first direction causes rotation of the flywheel, and is free wheeling when rotated in a second opposite direction. A pair of offset cranks are operatively connectable to the shaft and a pair of foot pedals are connected to the cranks. The exercise machine is operable in the first mode such that rearward movement of the runner causes rotation of the flywheel and forward movement of the runner rotates the roller independent of the rotation of the flywheel. Rotation of the cranks in the first mode causes rotation of the flywheel.
