How to Perform

Set the Smith machine bar just below shoulder height. Position the bar across your upper back, unrack it, and extend one leg forward while balancing on the working foot under the bar.

  1. Shift weight to working leg and extend non-working leg forward.
  2. Inhale and lower by bending hip and knee of working leg.
  3. Descend until thigh is parallel to floor or hamstring touches calf.
  4. Pause briefly at bottom.
  5. Exhale and drive through heel to extend knee and hip.
  6. Return to start position.
  7. Switch legs after reps.

Coaching Tips

Form Cues

  • Chest up, eyes forward
  • Knee tracks over toes
  • Core tight throughout
  • Heel drives ascent
  • Non-working leg parallel to floor

Breathing

Inhale during descent, brace core, and exhale forcefully during ascent.

Tempo

3-1-1

Range of Motion

Lower until working thigh is parallel to floor or as deep as mobility allows without losing spinal neutrality; fully extend knee and hip at top.

Safety

Safety Notes

  • Set safety stops at parallel height
  • Avoid if acute knee pain exists
  • Start with bodyweight
  • Maintain neutral spine

Spotting

Not typically needed; use machine safeties for failed reps.

Common Mistakes

  • Knee caving inward
  • Leaning forward excessively
  • Non-working leg dropping
  • Bouncing at bottom

When to Avoid

  • Knee joint instability
  • Acute lower back pain
  • Recent hip surgery

Flexibility Needed

  • Ankle dorsiflexion for depth
  • Hip flexion mobility

Build Up First

  • Master basic bilateral squat
  • Single-leg balance competency
