Equipment
How to do it
- Hold a dumbbell in each hand and let them hang at your sides.
- Stand with your feet shoulder-width apart and your toes turned slightly out.
- Squat down by bending your hips and knees, keeping your chest tall and back neutral.
- Lower until your thighs are at least parallel to the floor.
- Drive through your heels to stand up, extending your hips and knees.
- Keep the dumbbells still at your sides and your torso tight.
Common mistakes
- Leaning the torso too far forward
- Letting the knees cave inward
- Lifting the heels off the floor
What the evidence says
Over 10 weeks with MRI measurement, full squats grew the gluteus maximus and adductors about three times more than half squats, with the same quadriceps growth. And only the full-squat group got stronger at both depths.

Stopping at a quarter squat doesn't spread the stimulus evenly across the quads either: going down to 120° of knee flexion grew it along its whole length (~6%), while stopping at 60° grew it at only 2 of 6 measured sites.

The front squat isn't a watered-down version: it recruits muscle as much as the back squat with lower compressive force at the knee, even though you move less weight.

What isn't settled: Nobody has measured where the point of diminishing returns is. The studies compare extremes (full vs half, half vs quarter) over 10 to 12 weeks in people without years of squatting behind them; how much extra depth suits your hips and ankles isn't measured.
