Set up

  1. 01Set up the pec deck machine so you can move without reaching or shifting to find position.
  2. 02Stack the joints around the rear deltoids target and brace before the first repetition.
  3. 03Start with a load and range that you can repeat without compensating.

Execute

  1. 01Move through a controlled range while keeping the rear deltoids as the main target.
  2. 02Pause briefly at the strongest position instead of bouncing through it.
  3. 03Return to the start with the same control you used to begin.

Coach cues

  1. 01Stay stacked.
  2. 02Move with intent.
  3. 03Control the return.
  4. 04Stop one clean rep before form breaks.

Common mistakes

  1. 01Adding load before owning the range.
  2. 02Using momentum to finish a repetition.
  3. 03Letting posture change as fatigue rises.
  4. 04Rushing the eccentric phase.

Breathing

Keep the ribs stacked, inhale on the return, and exhale through the press or raise.

Tempo

Move smoothly with no swinging or bounce from the lower body.

Safety check

Use a pain-free range and avoid forcing overhead positions that change your posture.

Make it easier

Reduce load, shorten the range slightly, or choose a supported variation.

Make it harder

Add a pause, a slower eccentric, or a small amount of load only after every repetition is consistent.
