How to Perform

Set the Smith machine bar to chest height. Place your feet significantly wider than shoulder-width, pointing toes outward (45-60 degrees). Center the bar across your upper back, secure the safety catches, and unrack the weight.

  1. Brace your core and initiate the descent by pushing hips back and bending knees outward over the feet.
  2. Squat down until your thighs are parallel to the floor, maintaining an upright torso.
  3. Pause briefly at the bottom while ensuring knee alignment is maintained.
  4. Drive upward powerfully through your heels and glutes to return to the starting position.
  5. Fully extend hips and knees at the top of the movement.

Coaching Tips

Form Cues

  • Widen your stance
  • Knees track outward
  • Drive through heels
  • Chest up tall
  • Engage the glutes

Breathing

Inhale deeply while descending and brace your core; exhale as you drive the bar upward during the concentric phase.

Tempo

3-0-1

Range of Motion

Descend until the tops of the thighs are parallel or slightly below parallel to the floor, stopping before the lower back rounds.

Safety

Safety Notes

  • Always use the safety catches on the Smith machine.
  • Ensure feet are far enough forward to maintain balance and proper vertical path.
  • Do not allow the bar to rest on your neck.

Spotting

Not recommended; the Smith machine mechanism provides a safety catch system.

Common Mistakes

  • Knees caving inward
  • Too narrow a stance
  • Rounding the lower back
  • Not hitting depth (half reps)

When to Avoid

  • Acute knee pain or injury
  • Significant hip impingement
  • Severe lower back pain

Flexibility Needed

  • Adequate hip external rotation
  • Ankle dorsiflexion (moderate)

Build Up First

  • Basic squat pattern competency
  • Ability to brace the core effectively
