Turning the palms forward as the dumbbells lower changes the wrist and shoulder orientation at the bottom of the incline fly, which some lifters find allows a deeper upper-chest stretch than the standard neutral grip. Test it against the plain incline dumbbell fly for a few sessions and keep whichever grip stretches better without complaint from the shoulders.

How to do the Incline Twisting Dumbbell Fly

  1. Set an incline bench to a 45-degree angle and sit on it with a dumbbell in each hand, palms facing each other.
  2. Lie back on the bench and press the dumbbells up to the starting position, directly above your chest, with your arms extended.
  3. Lower the dumbbells out to the sides in a wide arc until you feel a stretch in your chest.
  4. As you lower the dumbbells, rotate your wrists so that your palms face forward at the bottom of the movement.
  5. Reverse the motion and bring the dumbbells back up to the starting position, squeezing your chest muscles together at the top.
  6. Repeat for the desired number of repetitions.

Tip: Imagine hugging a barrel rather than pushing a weight.

Muscles worked

Primary

Pectorals · Chest

On chest flies and cable crossovers the pecs pull the arms together in an arc and should feel a deep stretch at the bottom and a hard squeeze at the top.

Secondary

  • Delts — Rear delt flies work the back of the shoulder as the arms swing wide, and the front delt assists on any chest fly.
  • Triceps

Common mistakes

  • Elbows bending as you tire — this turns a fly into a press; set the elbow angle at the start and keep it constant for the whole set.
  • Going too heavy — flies are a stretch and squeeze movement, not a strength lift; you should be able to pause at the bottom without the shoulders rolling forward.
  • Stopping short of the stretch — let the arms open until you feel the chest or rear delts lengthen, then bring them back under control.
  • Not squeezing at the finish — the last few inches are where the muscle shortens most, so hold the contraction for a count before opening again.

Where it fits in a workout

Flies are an isolation movement for after the pressing or rowing is done. Pair a chest fly with a rear delt fly for a balanced superset.

Variations and alternatives

When to talk to someone

  • Chest discomfort, feeling faint or lightheaded, or trouble breathing during or after exercise can be signs of a heart attack. In the US, call 911 right away; elsewhere, call your local emergency number.
  • Heart, metabolic or kidney disease, or symptoms like these when you are active: talk to your doctor before you start or step up training.
  • Pregnant: ask your obstetric care provider which exercise suits you.
