How to do a squat with good form

Last updated: 21 October 2026

The barbell back squat is a full-body lower-body lift: the bar rests across the upper back while you bend the hips and knees and stand back up. It builds strength in the legs, hips and trunk, and it is best learned with light loads and someone experienced checking your position. Many lifters use it as a core part of a leg programme, which is why learning the setup early pays off.

How to do it

  1. Set the safety pins or arms in the rack just below the lowest point of your squat.
  2. Rest the bar across your upper back, on the muscle above the shoulder blades rather than the neck, and grip it just outside shoulder width.
  3. Unrack the bar, step back, and set your feet about shoulder width apart with toes turned out slightly.
  4. Brace your core, take a breath and keep your chest up.
  5. Sit your hips down and back, bending the knees in line with the toes, until you reach a depth you can control.
  6. Drive up through the whole foot, keeping the chest up and the bar over mid-foot.
  7. Rack the bar at the end of the set by stepping back into the rack.

Breathe in and brace before each rep, holding the breath through the bottom and breathing out once you are standing. Walk the bar out with small steps, since long steps can strain the lower back before the set starts. Rest long enough between sets to keep your position and bracing consistent. Filming a set from the side is a simple way to check depth and torso angle when no coach is present.

Form cues

Safety: Always squat inside a rack with the safety pins or arms set just below your lowest depth. Work with a spotter or an experienced lifter when you add heavy sets, and stop if you feel sharp pain in the knee or back.

Common mistakes

Muscles worked

Primary: Quadriceps and glutes.

Secondary: Adductors, hamstrings, the erector spinae and the core, which hold the torso steady under the bar.

Alternatives

Squat vs goblet squat

The barbell back squat carries the load on the upper back, so it can be heavier, but it needs a rack and practice holding posture under a bar.

The goblet squat holds a dumbbell or kettlebell at the chest, which helps keep the torso upright and is easy to learn. Many lifters start with the goblet version and move to the barbell once they can hold depth and posture. See the goblet squat guide.
