How to Perform

Position an incline bench at 30-45 degrees under the Smith machine bar. Lie back with feet flat, grip the bar slightly narrower than shoulder-width overhand.

  1. Unrack the bar by rotating wrists and extend arms straight up.
  2. Bend elbows to lower bar toward forehead, keeping upper arms stationary.
  3. Pause briefly at the bottom for a triceps stretch.
  4. Extend arms to push bar back up using triceps.
  5. Stop short of elbow lockout to maintain tension.
  6. Rerack the bar after completing reps.

Coaching Tips

Form Cues

  • Elbows tucked to sides
  • Upper arms stationary
  • Control the descent
  • Squeeze triceps at top
  • Avoid arching back

Breathing

Inhale as you lower the bar, exhale as you extend your arms.

Tempo

3-1-1

Range of Motion

Lower bar to forehead or slightly behind head until elbows are at 90 degrees; extend arms until nearly straight without locking elbows.

Safety

Safety Notes

  • Start with light weight to master form
  • Avoid excessive back arch
  • Do not lower bar beyond forehead if shoulder strain occurs
  • Consult doctor for elbow or shoulder pain

Spotting

Spotter can assist by standing at head end to help rerack or catch bar if needed, though Smith machine safeties reduce necessity.

Common Mistakes

  • Flaring elbows outward
  • Jerking the weight up
  • Locking elbows at top
  • Using momentum instead of triceps

When to Avoid

  • Acute elbow tendonitis
  • Shoulder impingement
  • Recent upper arm injury

Flexibility Needed

  • Shoulder flexion to 150 degrees
  • Wrist extension for grip

Build Up First

  • Basic elbow extension competency
  • Familiarity with Smith machine unracking
