This significant adjustment forces your quads, the muscle group on the front of your thighs, to manage and move more of the load, as well as making your core muscles work even harder to keep your torso upright and your upper body balanced.And there’s a bonus, too. Unlike the back squat, the position you’re in for the front squat forces you to stay upright and maintain the correct form, which means you can squat far more safely. ~ Berceste
