Barbell Squats

The barbell squat is the single most productive lower-body exercise in existence — quads, glutes, adductors, and trunk, all loaded together through a full range of motion. It demands more setup and mobility than any machine, and repays that cost with strength that transfers to everything else you do. Coached by Maddy (NASM-CPT) — these are the exact form cues he gives on every client's first week.

Level — Intermediate

Intermediate under a barbell — beginners should own the bodyweight and goblet patterns first.

Proper form — 5 cues

  1. Set the bar across the shelf of your upper traps, hands pulling it tight into your back.
  2. Stand about shoulder-width, toes turned out slightly, and screw your feet into the floor.
  3. Break at the hips and knees together, sitting down between your heels.
  4. Keep knees tracking over the toes and descend until your thighs reach at least parallel.
  5. Drive the whole foot through the floor to stand, hips and chest rising at the same rate.

Breathing: Big inhale and brace at the top, hold through the descent and drive, exhale past the sticking point.

The 3 mistakes Maddy corrects most

Knees caving inward out of the bottom. The valgus collapse loads the knee ligaments and robs the drive from your glutes. Fix: Lighten the load and cue 'spread the floor' with both feet; strengthen abductors alongside.
Heels lifting as you descend. The weight tips onto the toes, the torso pitches forward, and depth becomes impossible to control. Fix: Work ankle mobility, or squat with small plates under the heels while it improves.
Hips shooting up first out of the hole. The squat turns into a good-morning, transferring the load onto the lower back. Fix: Cue 'chest up as hips rise'; drop 10–15% of the load and rebuild the pattern.

Common questions

How deep should I squat?

To at least thigh-parallel, and as deep as you can hold a neutral spine and flat heels — for most people that is deeper than they think, once mobility is addressed. Depth cut short shifts the work toward the quads' top range and shortchanges the glutes. If your pelvis tucks hard at the bottom, stop just above that point and work mobility separately.

Are squats bad for your knees?

Trained sensibly, the opposite: squatting strengthens the quads, hamstrings, and the tissues around the knee, and current sports-medicine consensus supports deep squatting with good mechanics in healthy knees. Problems come from loads that outrun technique, knees collapsing inward, and zero progression logic — all fixable, none inherent to the movement.

High-bar or low-bar squat?

High-bar sits on the traps, keeps the torso more upright, and biases the quads; low-bar rests across the rear delts, hinges the hips more, and typically allows heavier loads. For general strength and muscle, high-bar is the simpler default. Low-bar earns its place if powerlifting-style loading is your goal.
