How To Perform

  1. 1 Reverse your position on the pec deck — face the pad rather than the pulleys.
  2. 2 Set the arms to the front position and grip the handles.
  3. 3 Spread the arms backward in a wide arc, squeezing the rear delts and upper back.
  4. 4 Return slowly to the start.

Form Cues

  • ✓ Maintain a tall, supported position — do not slouch.
  • ✓ The movement is a horizontal abduction — think of spreading your arms wide, not pulling them back.

Common Mistakes

  • ✗ Using too much weight and losing proper arc.
  • ✗ Bending the elbows excessively.
💡 Professor Splits Says:

Progressive overload is the engine of muscle growth. Track your weights and aim to add small increments weekly. For Reverse Pec Deck, this means gradually increasing load, volume (sets × reps), or decreasing rest periods over time.
