Abstract: An exercise device is set forth. It incorporates an inverted circular cowling which encloses the operative equipment and which centrally supports an upstanding fixed shaft serving as an axis for the rotating equipment. The shaft supports a circular platform for a user. Moreover, the device includes a pair of arms which extend from below the platform radially outwardly on the platform and bend upwardly to position a pair of hand grips for easy grasp by the upright user. The hand grips are rotated reciprocally in repetitive motion. This couples motion to a hub below the platform; the hub is connected through sprockets and drive chains to rotate a fly wheel under the cowling. The fly wheel is rotated first in one direction, then stopped, then rotated in the opposite direction, then stopped and rotated back in the first direction. This repetitive motion is a dynamic exercise routine for strengthening all areas of the body from the continual stopping and starting of the equipment.
