How to Perform

Position the barbell in a squat rack at shoulder height. Step under the bar, place it across your upper traps, grip outside shoulders, and unrack by straightening your legs.

  1. Brace your core and push hips back while bending knees to descend.
  2. Lower until thighs are parallel to the floor or hip crease below knees.
  3. Push knees out in line with toes throughout descent.
  4. Drive through midfoot to extend hips and knees simultaneously.
  5. Squeeze glutes at the top without arching lower back.
  6. Walk forward to rerack the bar after reps.

Coaching Tips

Form Cues

  • Chest up
  • Knees track toes
  • Push through heels
  • Brace core tight
  • Neutral spine always

Breathing

Inhale deeply to brace core before descending; exhale forcefully during ascent.

Tempo

3-1-1

Range of Motion

Descend until hip crease is at or below knee height with neutral spine; ascend to full hip and knee extension.

Safety

Safety Notes

  • Use safety pins set below squat depth
  • Start with light weights to master form
  • Avoid if acute knee or lower back injury
  • Ensure even plate loading
  • Inspect rack and bar before use

Spotting

Use power rack safeties; spotter optional for heavy sets, positioned behind to assist on failed reps.

Common Mistakes

  • Rounding lower back
  • Knees caving inward
  • Heels lifting off floor
  • Incomplete depth
  • Overarching at top

When to Avoid

  • Acute lower back pain
  • Severe knee instability
  • Recent hip surgery

Flexibility Needed

  • Ankle dorsiflexion for depth
  • Hip flexion beyond 90 degrees
  • Thoracic extension

Build Up First

  • Mastery of bodyweight squat
  • Core bracing technique
  • Upper back strength for bar support
