Barbell Squat

The back squat is the reference lift for lower body strength. With the bar resting across the upper traps, the quads drive the ascent while the glutes, adductors and spinal erectors hold everything in position through the full range. It loads more muscle at once than almost any other exercise, which makes it as useful for general conditioning as it is for building leg size.

Technique

How to Do the Barbell Squat

  1. Set the rack so the bar sits at roughly mid chest height and load it evenly.
  2. Step under the bar and place it across your upper traps, not on your neck, then grip it firmly with your hands just outside your shoulders.
  3. Stand up to unrack the weight and take two steps back into a stance a little wider than your hips with your toes turned slightly out.
  4. Take a big breath, brace your core, and sit down and back by bending at the hips and knees together.
  5. Descend until your thighs are at least parallel to the floor, keeping your chest up and your knees tracking over your toes.
  6. Drive through your midfoot to stand back up, exhaling as you pass the hardest point of the rep.

Do This

Form Cues

  • Screw your feet into the floor to create tension at the hips before you start the descent.
  • Brace before every rep, not just the first one.
  • Knees track in line with your toes. Letting them cave inward is the most common breakdown under fatigue.
  • Keep the bar stacked directly over your midfoot from start to finish.

Avoid This

Common Mistakes

  • Cutting depth short and stopping well above parallel as the weight climbs.
  • Letting the chest fall forward so the squat drifts into a good morning.
  • Rising onto the toes at the bottom, usually a sign of tight ankles or a stance that is too narrow.
  • Resting the bar on the bony part of the neck instead of the shelf of muscle across the upper back.
