ABSTRACT:
A therapeutic and exercise device which is substantially a two-step hollow ladder partially filled with a viscous fluid such as water and also containing ballast such as ball bearings for adding additional weight, with the fluid and ballast shifting from one end of the ladder to the other when one end is held lower than the other, thus increasing weight slowly from one end to the other. The two-step hollow ladder also includes valves to control the rate of flow.
