Two-way resistant weight workout

If exercise equipment utilized shock absorbers, it could provide resistance in both directions.

Fluid flow through the piston controls the resistance of shock absorbers. It can be adjusted for different resistance in each direction. For example, one direction could simulate 30lbs of weights and the other direction 15lbs.

Also, the resistance would be constant throughout the lift, unlike rubber bands. Like bands, the equipment does not need to be as heavy or cumbersome.

This could be applied to an entire line of equipment. Or, the shock absorbers could be stand alone or hook to a wall mount of foot holder to giving more freedom of movement.
