Low bar squat form: technique, common mistakes, and tips
The low bar squat is not a high bar squat with the bar an inch lower. The shift in bar position changes the hip angle, the moment arm, and the muscles you're actually loading. Most trainees can load 10-20% more weight this way, but only if the form is dialed. That means a forward torso lean of about 10 degrees at the bottom, not an upright chest. Dorsi uses wrist-mounted IMU data to track your torso angle on every rep. Before we walk through the setup, the descent, and the ascent, here's the one thing that makes or breaks the lift, and most coaches don't talk about it.
Practical Playbook
Where should the bar rest on your back?
Low bar sits across your posterior deltoids, not on your traps. Find the spot about two inches below the spine of your scapula. If the bar migrates up mid-set, you're too vertical. Drop it lower, it should feel like it's wedged into a shelf, not balanced on bone.
Set your stance and grip width.
Stance a bit wider than hip width, toes pointed out about 30 degrees. Grip just outside shoulder width, wrists neutral, don't let them bend back. If your elbows flare, widen your grip. If your shoulders round, narrow it. Find the slot where you can stay tight without pain.
Brace your core before every rep.
Big breath into your belly, not your chest. Brace like someone's about to punch you in the gut. Hold that tightness through the entire descent. Don't let your ribs flare or your lower back round. Exhale only after you've locked out the top. One breath per rep.
Drive with your hips, not your chest.
During the ascent, think hips up, not chest up. If your hips rise faster than your shoulders, you'll turn the squat into a good morning. Push your back into the bar, keep your torso angle constant, and let your glutes and hams do the work. Most missed reps happen here.
Common Mistakes
- Mistake
- Setting the bar too high on your traps.
- Why
- Forces your torso too upright, turning a low-bar squat into a high-bar squat. You lose the mechanical advantage of the hip drive the low bar is designed for.
- Fix
- Place the bar across the posterior deltoid shelf, about an inch below the spine of the scapula. You'll feel it sit in that little groove.
- Mistake
- Not creating a muscle shelf with your rear delts.
- Why
- Without that shelf, the bar digs into your spine or rolls up during the squat. It's unstable and painful.
- Fix
- Pull your shoulder blades together and push your elbows back, like you're trying to snap a pencil between your shoulder blades. That creates a solid platform.
- Mistake
- Letting your chest cave forward as you come out of the hole.
- Why
- This turns the squat into a good morning, shifting the load to your lower back. You'll miss the lift or grind your vertebrae.
- Fix
- Keep your chest proud and drive your upper back into the bar on the way up. Think 'show the logo on your shirt to the wall in front of you.'
- Mistake
- Breaking at the knees first instead of hips and knees simultaneously.
- Why
- Folds your body like a lawn chair. The bar drifts forward over your toes, and you lose tightness in the posterior chain.
- Fix
- Imagine sitting back into a chair that's just out of reach. Your hips and knees should start moving at the same moment.
