Pairing the omni-directional motion of Core-Tex with the vibration of Power Plate during a glute bridge/hip thrust allows for the movement of the torso to create variability to the joints and muscles during the exercise. This version of this popular exercise is great for challenging the posterior chain in novel ways.
You are going to love the variety of movements demonstrated here by some of the biggest champions in the Reactive Training Community.
