Reviewed by Bryan Cortez, MS
Highest stimulus and highest fatigue in the gym — respect both.

How to do it
Setup
- Bar on upper traps (high-bar) or rear delts (low-bar)
- Stance shoulder-width, toes slightly out
- Brace abs hard, big breath into the belt
- Unrack, walk out in 2-3 steps
Execution
- Break at hips and knees together
- Sit down between the hips, knees track over toes
- Descend to depth you can keep a neutral spine
- Drive the floor away, hips and chest rise together
Common Errors
- Knees caving in (weak abduction/cueing)
- Hips shooting up first (turns it into a good-morning)
- Heels lifting (ankle mobility)
- Losing the brace at the bottom
Cues That Work
- 'Spread the floor' (knees out)
- 'Big air, brace like you'll be punched'
- 'Chest and hips rise together'
- 'Screw your feet into the floor'
No-Fly Zone
over 15 reps (becomes a cardio grind and form breaks down under spinal load)
Programming
Sequence priority
Opens the session
Highest skill, axial load, and CNS demand of leg day — form and max output collapse under fatigue, so it goes first while you're fresh.
Progression
Model — Linear
Fallback model — Double
Beginner: add 5-10 lb every session at the same reps. Stall 2 sessions in a row at target RIR → switch to double progression in the 5-8 range, then nudge load.

If it hurts
Pain is information, not a challenge to push through. Stop the set if pain is sharp, worsening, or changes how you move. These are exercise-selection options, not medical diagnosis or rehabilitation advice.
Work down this list in order. Stop at the first change that removes the pain.
Step 1
Setup tweaks
Widen or narrow stance; toes more out; high-bar vs low-bar; heeled shoes or small plates under the heels for ankle mobility.
Step 2
ROM / tempo / bias
Squat to a pain-free depth; pause squat to kill the bounce; slow tempo eccentric for control.
Step 3
Implement swap
Barbell → hack squat or leg press (locks the path, unloads the spine) → Smith machine for a fixed bar path → goblet squat to scale down.
Substitutions
Approved fallback
Barbell → hack squat or leg press (locks the path, unloads the spine) → Smith machine for a fixed bar path → goblet squat to scale down.

Builds total lower-body mass and strength with a big systemic stimulus. Does NOT isolate the quads, and the fatigue cost means more is not always better.
