Xtreme™ Strong Resistance Cable System activates your core muscles – abs, lower back, hips and obliques in order to allow you to isolate the targeted muscle that you are working. Training on a cable-based machine provides you with a more functional form of exercise since the movement patterns are more akin to real life movements – lunging, squatting, pushing, pulling, bending and twisting.  Your movements are not constrained by a machine.
