Quick Answer: A cue is not a rule — it is a temporary correction aimed at one error. Cues like knees out, chest up and sit back were designed to fix specific faults, and they cause new problems when given to lifters who did not have those faults to begin with. The better approach is to cue the outcome you want rather than the body part, and to change the cue as soon as the error is gone.

You have heard all of these. Some of them helped once.

The trouble is that a cue that fixed your squat in March can be the thing quietly breaking it in August.

The fifth one on this list is the one most experienced lifters are still carrying around unnecessarily.

1. Knees out

Why it was invented: to stop knees collapsing inward, which is a genuine and common fault, particularly under heavier loads.

Why it backfires: applied to someone who does not collapse inward, aggressive knees-out pushes the knees wide of the feet, which loads the outside of the knee and often shortens depth. Some lifters end up shifting weight to the outer edge of the foot and losing the arch entirely.

Say instead: spread the floor. It produces the same external rotation but keeps pressure distributed across the whole foot, because you are cueing the floor rather than the joint. If the knees are already tracking over the toes, you probably do not need this cue at all.

2. Chest up

Why it was invented: to stop a lifter folding forward and turning a squat into a good morning.

Why it backfires: most people execute chest up by extending at the lower back rather than the upper back. That gives you an exaggerated arch, a rib flare, and a loss of core bracing right where you need it most.

Say instead: proud chest, ribs down, or simply stay tall through the top of your head. Both get you the thoracic position without the lumbar cost. If you want an external cue, ask the lifter to keep a logo on their shirt facing the mirror throughout.

3. Sit back

Why it was invented: for low-bar squatting and for lifters whose knees shoot forward before their hips move at all.

Why it backfires: in a high-bar or front squat it produces a forward lean you cannot recover from and turns the movement into something between a squat and a hinge. It also frequently reduces depth, because sitting back closes the hip earlier.

Say instead: hips and knees together, or sit between your feet. For most general trainees, the goal is simultaneous hip and knee flexion, not a hip-dominant sequence.

4. Push through your heels

Why it was invented: to stop lifters rising onto their toes and pitching forward at the bottom.

Why it backfires: taken literally, it unloads the front of the foot and can make you rock back, which the body corrects by leaning further forward — the exact fault you were trying to fix. It also tends to reduce how well the quads contribute.

Say instead: whole foot, big toe and heel both down, sometimes called tripod foot. The intent is even pressure, not a shift to the back of the shoe.

5. Brace your core

Why it was invented: entirely reasonably, because trunk stiffness is what protects the spine under load.

Why it backfires: it is far too vague, and most people interpret it as sucking the stomach in, which is close to the opposite of what you want. Others hold their breath at the wrong moment or brace so hard on warm-up sets that they are tired before the working set.

Say instead: take air into your belly, then push out against your belt or your hand. Give a concrete physical target for the pressure to push against. And scale it — a genuine hard brace belongs on your top two or three sets, not on the empty bar.

The last two: go as deep as you can, and just squat more

6. Go as deep as you can

Why it was invented: to stop the very common habit of quarter squatting.

Why it backfires: for lifters whose depth is already fine, chasing more depth produces a posterior pelvic tilt at the bottom, sometimes called a butt wink, and a loss of tension exactly where the lift is hardest.

Say instead: go to the deepest point you can hold position. Depth is a consequence of mobility and control, not a target to be forced. Filming from the side at hip-crease height tells you more in one session than a month of guessing.

7. Just squat more

Why it was invented: because specificity is real, and many people genuinely do not squat often enough to build the pattern.

Why it backfires: repeating a broken pattern rehearses the break. If your right hip shifts under load, a hundred more loaded reps make the shift more automatic, not less.

Say instead: fix it light, then load it. Two or three sets at a weight where the fault disappears, twice a week, for three to four weeks, is usually enough to change the pattern. Then add load back in gradually while filming to confirm the fault has not returned.

Myth vs Fact, quickly: the myth is that a good lifter has a permanent set of cues. The fact is that the best lifters cycle through cues constantly, dropping each one the moment it has done its job.

FAQ: Squat Cue Questions, Answered

How many cues should I use at once?

One. Two at the absolute most. Working memory under a loaded bar is very limited, and a lifter given three cues typically executes none of them well.

How do I know when a cue has done its job?

When the fault does not appear on video for two or three consecutive sessions without you thinking about the cue. At that point, keeping the cue risks over-correcting into the opposite fault.

Are external cues really better than internal ones?

For most trainees, yes. Cues aimed at the environment — spread the floor, push the floor away, stay tall — tend to produce better movement than cues aimed at a body part, because they let the nervous system solve the problem rather than micromanaging it.

This is general information, not medical advice. If a squat consistently produces pain rather than difficulty, see a qualified professional before adding load.

TL;DR:

• A cue is a temporary fix for a specific fault, not a permanent rule of good technique.
• Knees out, chest up and sit back all cause new problems when given to lifters who did not have the original fault.
• External cues — spread the floor, stay tall, push against your hand — outperform body-part cues for most people.
• Use one cue at a time, film from the side, and retire each cue as soon as the fault stops appearing.

If your squat has felt stuck for months, there is a decent chance you are still applying a correction to a problem you solved a long time ago.
