HOW: Start in a standing position with a band anchored under your feet and around the top of your upper back. Hold onto the band in each hand - try to position the band similarly to how you would position a barbell in a back squat. To begin the exercise, squat down similarly to how you would perform a back squat, then return to starting position and repeat. There will be slack on the band at the bottom of the squat, use the resistance cue to stand aggressively to push against the resistance.
FEEL: This should feel like a lower body workout, specifically your glutes and your quadriceps muscles.
COMPENSATION: All of the same rules apply with your traditional back squat form, shoulders stacked over knees over toes, it is ok to lean forward a bit. It is also ok for your knees to go forward, but also let your hips bend and push your butt back. Do not let your knees cave in or your torso lean side to side. Maintain good low back and shoulder blade position.
