How to do it

Setup

  1. Adjust the seat height so the machine handles align horizontally with mid-chest level.
  2. Sit back firmly against the backrest with your feet planted flat on the floor.
  3. Grasp the inner or narrow handle attachments with a neutral grip and maintain a slight bend in your elbows.

Movement

  1. Engage your chest and pull the handles together in a smooth arc until your hands nearly touch in front of your sternum.
  2. Squeeze your pectoral muscles intensely at peak contraction for a brief pause.
  3. Slowly reverse the movement under control, allowing your chest to open until you feel a comfortable stretch without letting the weight stack touch down.

Breathing

Exhale as you bring the handles together; inhale as you slowly return to the stretched starting position.

Cues

  • Lead with your elbows, not your hands.
  • Keep your chest high and shoulders pinned back.
  • Squeeze the chest at the center.

Common faults

Allowing the shoulders to shrug or roll forward at the end of the press.
Keep your shoulder blades retracted and depressed against the backrest throughout the movement.
Overextending the arms backward and hyperextending the shoulder capsule.
Stop the eccentric phase when your elbows are roughly in line with your torso, feeling tension in the chest rather than the shoulder joint.
Letting the weight plates crash between repetitions.
Maintain continuous muscular tension by stopping just short of the weight stack resting.

Safety

  • Do not set the starting arm range too far back if you have a history of anterior shoulder instability.
