How to do it

Feel it right

Where you should feel it, the one cue to remember, and quick fixes when you feel it somewhere else.

You should feel it inBack of arms

Back of the upper arm, especially near the armpit.

Key cue (the coach says it during the set)“Elbows still, only the forearms move, lock out and squeeze.”

Tempo · Bend 2 s · extend 1 s · squeeze 1

Choosing the load: Pick a weight you finish with 1–2 good reps left. 4+ left = too light; form breaks = too heavy.

Feel it somewhere else? Fix it like this

  • Feel it in ShouldersElbows flaring or moving. Point them forward (overhead) or pin them to your sides (pushdown / bench dip).
  • Feel it in ElbowsElbow ache. Use a rope or EZ bar, warm up with light sets, and do not bounce at the bottom.
  • Feel it in ChestChest taking over (bench dips / close presses). Keep the torso upright and elbows close.
  • Barely felt itToo light or too fast. Lower for 3 seconds, pause 1 second at the stretch, and pick a load that leaves only 1–2 reps in the tank.
  • Joint painSharp or joint pain is a stop sign: end this set, lower the weight, shorten the range — if it repeats, switch to an easier variation.

During a workout we ask after the first set where you felt it and give the fix right away — and remember it for next time.

Tips

  • Sit tall with your back supported so the target muscle does the work.
  • Keep your back against the pad so your shoulders stay out of the movement.
  • The fixed path makes it easy to train close to failure safely.
  • Adjust the seat so your joint lines up with the machine’s pivot point.

Common mistakes

  • Lifting the elbows off the pad to push with the shoulders.
  • Letting the weight stack crash down between reps.

Breathing

Exhale as you extend, inhale as you return.
