Should you be Squatting Below Parallel?

Walk into most gyms and you’ll hear some version of the same thing: if you aren’t breaking parallel, you aren’t really squatting. It gets treated like a character test. Dr. Stuart McGill’s work on hip anatomy says that’s the wrong test.

What McGill Actually Said

In Assessing Movement, McGill argues the deep squat is primarily governed by genetics. Shallow hip sockets (what hip surgeons call a Dalmatian hip) let the femur travel farther before bone meets bone. McGill points to that architecture when he talks about why so many great Olympic lifters come out of Poland, Bulgaria, and Ukraine. Deep sockets, more common in Celtic hips, are excellent for walking, standing, and rotational power, and terrible at producing power at the bottom of a deep squat.

This isn’t a coaching slogan. It’s bone shape. McGill is not saying Scots can’t lift. He is saying your socket depth and orientation set a hard stop that stretching will not file away.

What Happens When You Force Depth Anyway

When the femur runs out of room in the acetabulum, the pelvis tucks under. That posterior tilt flexes the lumbar spine. Now the discs are taking compression and shear in a rounded position, under load. McGill’s line is the one I use with clients: in many cases, the failure of an individual to deep squat cannot be corrected.

You can stretch. You can cue “chest up.” You cannot change the roof of a hip socket in the gym. If the only way you get below parallel is by letting the low back become the hinge, you did not earn more range. You borrowed it from your spine.

So Does Anyone Need Below Parallel?

Some people do, and their hips allow it. Olympic lifters need to receive a bar in a deep catch. Powerlifters need whatever depth the rulebook and their anatomy can agree on. Most adults I train in Anne Arundel County need a squat they can load without their low back becoming the hinge.

Below parallel is useful when your hips get there without the pelvis tucking, the sport or the lift actually requires that range, and you can keep a stiff trunk at that depth. It is not useful when the only reason you’re going there is a video you watched.

How I Coach It

I watch the last two inches. That’s where the story shows up. If the pelvis starts to wink, we stop a little higher, change stance width, or switch the variation (box squat, heels elevated, goblet) until the hips, not the lumbar spine, own the bottom. That’s what a movement screening is for: finding the depth you actually own, not the depth the internet assigned you.

Bottom Line

Nobody needs to squat below parallel as a moral rule. Some people can, some people shouldn’t, and the difference is mostly the socket you were born with. McGill is not saying deep squats are bad. He is saying forcing one past your hip anatomy is how you turn a strength exercise into a spine-loading problem.

If you want that checked instead of guessed, start with a $90 screening. Call (240) 481-1799 or email Brian.movementmatters@gmail.com.
