Abstract
An exercise device includes a pair of parallel tracks each having a shaft disposed in the middle portion, a pair of parallel poles slidably engaged on the shafts, springs biasing the poles away from each other, a pair of slides slidably engaged on the tracks, a number of elastic bands having one end fixed to each of the slides and the other end fixed to the tracks. The elastic bands are arranged such that the poles move toward each other against the springs when the slides are moved away from each other.
