An improved wheeled exercise device which is adjustable for users of different size and muscle capability. The device comprises a wheel rotatably mounted on an axle, a pair of handgrips telescopically mounted on the axle, and a length of elastic tubing telescopically mounted on the opposite ends of the axle. A pair of pads are adjustably mounted on the elastic tubing. The pads may be moved to different points along the length of the tubing to accommodate users of different size and strength. The user kneels or stands on the pads, grips the handgrips, and rolls the wheel and axle forward, away from the pads until the user is in the prone position. Thereafter, the user rolls the axle and wheel backward, until the starting position is reached.
