pwr_machine said:"pause".
i have never paused on a box squat or seen anyone at the gym do it either. sit on the box, relax your hips, then flex HARD and violently off the box, no puase. to me puase means to stop and keep everything the same, you do that with everything except the hips. so the way i see it, its not a pause. it LOOKS like a pause, but theres alot more going on the meets the eye. much like when a swan or duck is swimming through the water, from above doesnt seem like much is going on, but look under the water and its chaos.
