Barbell back squat

The barbell back squat works your quads and glutes, with your inner thighs, lower back, and abs and core helping. Start with 2 to 3 sets of 8 to 12 reps, stopping with about 3 reps in reserve. To build muscle, do 2 to 4 sets of 6 to 12 reps.

Video on the way

We film every move with real women. Until then, follow the steps and the 3 tips.

  1. Tip 1Brace before you sit down
  2. Tip 2Knees track over your toes
  3. Tip 3Push the floor with your whole foot

Where you should feel it

In the front of your thighs and your glutes, strongest coming out of the bottom. Your adductors and lower back work to keep you steady. Squatting deeper brings in more glute.

Main muscles
Vastus lateralis, vastus medialis, and gluteus maximus
Also working
Rectus femoris, adductor magnus, adductors, spinal erectors, rectus abdominis, and obliques

How to do it

  1. Set the bar in the rack at mid-chest height, settle it on your upper back just below your neck and grip it a little wider than your shoulders.

  2. Unrack the bar, take 2 or 3 steps back and set your feet shoulder-width apart, toes turned slightly out.

  3. Take a breath, brace your core and sit down by moving your hips back and down, knees tracking over your toes.

  4. Go as deep as you can while keeping a neutral spine and your heels down, ideally with your thighs at or below knee level.

  5. Stand up by pushing the floor away with your whole foot and breathe out near the top.

Common mistakes

  • Mistake

    Knees caving in on the way up.

    How to fix it

    Think about spreading the floor with your feet and keep your knees in line with your toes. If you can't, lower the weight.

  • Mistake

    Heels lifting at the bottom.

    How to fix it

    Widen your stance a little and only go as low as you can with your heels down. Build depth gradually.

  • Mistake

    Hips shooting up before your chest out of the bottom.

    How to fix it

    Lift your chest and hips together, as if pushing your upper back into the bar.

Sets and reps for your goal

Getting started2 to 38 to 12360 to 120 s
Muscle and definition2 to 46 to 121 to 31.5 to 3 min
Max strength3 to 53 to 62 to 32.5 to 4 min

Max strength (3 to 6 reps) only once your form is solid, always with 2 to 3 reps in reserve.

Reps in reserve: how many more reps you could still do with good form when you end the set.
