Squat form: proper technique, common mistakes and how to adapt it to your body
There is no single correct squat, but there are principles that always hold. Here they are, plus the variations that fit your mobility and anatomy.
The squat is not an exercise with one valid shape. It depends on femur length, ankle and hip mobility, and the goal of the set. What does not change are the principles: the bar travels over the middle of the foot, the spine keeps its natural curve, and the knees track in line with the feet.
Setup: five checkpoints
- Feet shoulder-width or slightly wider, toes turned out 15 to 30 degrees.
- Bar on the traps (high bar) or on the rear delts (low bar), never on the neck.
- Ribs down and brace hard: inhale through the nose and tighten as if bracing for a punch.
- Start the descent by moving hips and knees together, not one before the other.
- Push the floor with the whole foot: the heel stays down and the arch does not collapse.
How much depth do you need?
Descending until the hip crease is below the knee maximizes quad and glute stimulus, but only if you can do it without the pelvis tucking under (butt wink). If your mobility does not allow it, squat to the depth you control and train ankle mobility separately. A controlled range always beats a forced one.
| Problem | Usual cause | Fix |
|---|---|---|
| Heels lift | Limited ankle dorsiflexion | Heeled shoe or wedge; soleus mobility work |
| Knees cave in | Weak glute medius or narrow stance | Band around the knees, widen the stance |
| Torso pitches forward | Long femur or forced high-bar position | Try low bar or the front squat |
| Low back pain on the way up | Loss of intra-abdominal pressure | Relearn bracing with light loads |
Quick ankle mobility test
Kneel facing a wall with the foot pointing straight ahead: if you can touch the wall with your knee while the toes are 10 cm away, your dorsiflexion is enough for a deep squat.
Variations for your case
- Goblet squat: the best way to learn the pattern and to warm up.
- Front squat: more upright torso, very useful if your low back complains.
- Hack squat or leg press: the alternative when axial loading is the problem.
- Bulgarian split squat: unilateral, ideal for fixing asymmetries and building stability.
Belt and shoes: when they make sense
A 10 mm belt helps once loads get heavy (above 1.2 times your bodyweight), and flat, firm-soled shoes transfer force far better than cushioned running trainers.

Sharp knee or low back pain during squats is not fixed with more reps. Stop the exercise and see a physiotherapist who can assess you in person.
Frequently asked questions
- Can my knees travel past my toes?
- Yes. It is a normal and necessary movement in any deep squat; what matters is that the knee tracks in line with the foot.
- Do I have to barbell squat?
- No. It is very efficient, but leg press, hack squat and split squats can build your legs if the barbell does not suit you.
- How many squat sets per week?
- Four to eight hard sets is reasonable inside a weekly total of 10-18 sets for legs.
