A blow-moldable container, having a centrally located, generally tubular handle spanning a central recess has improved balance and ergonomics over existing blow-molded containers. Such a balanced container has great utility as a handheld freeweight, or as a container for pourable substances. An integrally molded base allows our container to be stood upright on end like a regular bottle. Products may be marketed in such containers under the premise that the consumer automatically acquires a freeweight by purchasing the product. The inclusion of fitably engageable contours on its top and bottom surfaces makes such a container stackable with others of its kind, for ease of packaging, shipping, and storage. A graduated set of handheld fillable freeweights may thus be compactly stored without a special rack. Since blow-molding offers great economy of production for sufficiently large numbers of containers, the average person will now be able to afford an entire graduated set of freeweights. Such freeweights may be shipped empty, and filled with water by the consumer, slashing shipping costs, and thereby further reducing the cost to the consumer. Blow-moldable, two-handed freeweights (barbells) are also disclosed. These also may be provided with contours offering enhanced stackability. Voids to fitably engage a user's feet further add to their utility. A deck member, as well as base members, may be stackably combined with the freeweights to form a stepping platform for aerobics, or an exercise bench. Methods for attaching fillable auxiliary weights to our handheld freeweights are also shown.

An improved lift apparatus for use in an exercise device having a support base and a moveable element, wherein the moveable element can be selectively raised and lowered relative to the support base by the user during operation of the exercise device, and wherein each of the support base and the moveable element have opposing first and second sides, the improved lift apparatus comprising: a first lift motor coupled between the support base and the moveable element; a second lift motor coupled between the support base and the moveable element; and means for synchronizing the first and second lift motors, wherein the means for synchronizing comprises a sway bar, the sway bar having a longitudinal axis, wherein the sway bar pivots about an axis other than said longitudinal axis. 2. An improved lift apparatus as recited in claim 1, wherein the means for synchronizing comprises: a cross support rigidly connected to the first and second sides of the support base; and wherein the sway bar has a first end, a center, and a second end, wherein the sway bar is pivotally coupled to the cross support, and wherein the first lift motor is coupled to the first end of the sway bar and the second lift motor is coupled to the second end of the sway bar, such that the sway bar compensates for variation between the first and second lift motors. 3. An improved lift apparatus as recited in claim 1, wherein the means for synchronizing comprising: a cross support rigidly connected to the first and second sides of the support base; wherein the sway bar has a first end, a center, and a second end, wherein the sway bar is pivotally coupled to the cross support, and wherein the first lift motor is coupled to the first end of the sway bar and the second lift motor is coupled to the second end of the sway bar, such that the sway bar compensates for variation between: (i) the displacement of the first motor; and (ii) the displacement of the second motor. 4. An improved lift apparatus as recited in claim 1, wherein the means for synchronizing comprises: a cross support rigidly connected to, and extending between, the first and second sides of the support base and having a first end, a center, and a second end; wherein the sway bar has a first end, a center, and a second end, wherein the sway bar is pivotally coupled to the cross support, and wherein the first lift motor is coupled to the first end of the sway bar and the second lift motor is coupled to the second end of the sway bar, such that the sway bar compensates for relatively minor variations in the operation of the first and second lift motors. 5. An improved lift apparatus as recited in claim 1, wherein the first and second lift motors are pivotally coupled to the movable element.6. An improved lift apparatus as recited in claim 1, further comprising a tolerance regulator.7. An improved lift apparatus as recited in claim 6, wherein the tolerance regulator comprises first and second contact switches, wherein an end of the sway bar will trigger one of the first or second contact switches in the event that the variation in operation of the first and second lift motors exceeds a given rotation parameter.8. An improved lift apparatus as recited in claim 7, wherein the tolerance regulator disengages the first and second lift motors upon triggering one of the first or second contact switches.9. An improved lift apparatus as recited in claim 1, wherein the means for synchronizing the first and second lift motors further comprises a control module for monitoring the first and second lift motors and maintaining the first and second lift motors within a predefined parameter relative to one another.10. An improved lift apparatus as recited in claim 1, wherein the first and second lift motors comprise lead-screw type lift motors.11. An improved lift apparatus as recited in claim 10, wherein the means for synchronizing the first and second lift motors further comprises a control module f
