How to perform the Barbell Back Squat
- Set the bar in the rack just below shoulder height; duck under it and place it either on the upper traps (high bar) or on the rear delts across the spine of the scapula (low bar).
- Grip the bar evenly outside shoulder width to create a shelf with the upper back; squeeze the elbows down and the chest up.
- Unrack the bar with both feet under it, take two or three steps back to clear the rack, and set your feet roughly shoulder-width with toes slightly turned out.
- Take a deep breath into your belly, brace your core hard, then break at the hips and knees simultaneously, sitting between your legs rather than pushing the hips straight back.
- Descend until your hip crease is at or below the top of the knee, keeping the knees tracking over your toes and the bar path vertical over the mid-foot.
- Drive up by pushing your feet through the floor and standing tall; lead with the chest and the hips rising together, not the hips shooting up first.
- Re-rack only when both feet are under the bar and you are walking forward into the J-hooks — never let go until the bar is fully seated.
Suggested working range: 5–8 reps. Default progression: double progression.
Common mistakes
- •Letting the knees cave inward (valgus collapse) at the bottom or during the drive out of the hole.
- •Shooting the hips up first out of the bottom so the torso pitches forward and the squat turns into a good morning.
- •Cutting depth short by a quarter or half squat instead of breaking parallel.
- •Letting the heels lift off the floor at the bottom, usually a sign of ankle mobility limitations or a too-narrow stance.
- •Letting the chest drop and the upper back round under heavy load.
