US5498162


1. A process for demonstrating a lifting technique to a person, the process comprising the steps of: providing a substantially rectangular box in a first stationary position on a ground surface, the box having an internal storage area means for receiving a plurality of weights therein, the internal storage area means formed by a top wall, a bottom wall, a front wall, a back wall, and first and second opposed side walls, the first and second side walls each having handles thereon adjacent the top wall, the bottom wall contacting the ground surface in the first stationary position, the bottom wall being movable to provide access to the internal storage area means; inserting at least one weight into the internal storage area means, wherein the internal storage area means receives said plurality of weights therein to selectively change the weight of the box and the resistance one's body perceives when raising and lower the box from the first stationary position and to the first stationary position, the bottom wall having a securing means such that the at least weight is contained within the box when the box is lifted; approaching two perpendicular sides of the box, wherein one of the perpendicular sides is one of the front or back walls, in the first stationary position at approximately a 45 DEG angle such that one's feet are wider than shoulder distance apart when one is adjacent the box; bending one's knees such that one's body is close to the box; lifting the box from the first stationary position using the handles; and returning the box to the first stationary position.
