Explosive movements cannot be carried out with free weights or a cable system, as the movement is faster than gravity. Develop powerful legs and hips using Slastix technology as the form of resistance and avoid damaging expensive equipment.

The unique three-ring ankle strap allows the Slastix elastic to be connected to all the key locations of the foot, providing resistance in every possible movement. The All Legs Speed Builder comes with two straps, two 4’ Slastix and one anchor.
