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 inFront of arms

Front of the upper arm pumping up.

Key cue (the coach says it during the set)“Elbows pinned, curl up, squeeze, lower slowly.”

Tempo · Up 1 s · squeeze 1 · down 3 s

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 drifting forward and the shoulders lifting. Keep the elbows at your sides and lighten the weight.
  • Feel it in Forearms / gripWrists curling in. Keep the wrists straight and loosen the grip slightly.
  • Feel it in Lower backSwinging the torso. Stand against a wall or sit, and use a weight you can lift without momentum.
  • 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

  • Set the bench to about 30–45° to shift the emphasis upward.
  • Alternate sides every rep and keep your torso steady.
  • The stretched position hits the long head hard — go lighter than on standing curls.
  • Keep your shoulders pinned back against the pad throughout.

Common mistakes

  • Bringing the elbows forward as the weights come up.
  • Using a weight so heavy that you cut the bottom stretch short.

Breathing

Exhale as you curl up, inhale as you lower.
