Rotating your palms from facing each other to facing forward as the dumbbells descend changes the shoulder position at the bottom of the decline fly, which lets some lifters settle into the stretch more comfortably. The twist adds nothing if it turns into momentum, so keep the rotation slow and the weight a notch below your standard decline dumbbell fly.

How to do the Decline Twisting Grip Dumbbell Fly

  1. Lie down on a decline bench with your head lower than your hips.
  2. Hold a dumbbell in each hand with your palms facing each other and your arms extended straight up over your chest.
  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, twist 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 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

  • DeltsRear 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 tirethis turns a fly into a press; set the elbow angle at the start and keep it constant for the whole set.
  • Going too heavyflies 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 stretchlet the arms open until you feel the chest or rear delts lengthen, then bring them back under control.
  • Not squeezing at the finishthe last few inches are where the muscle shortens most, so hold the contraction for a count before opening again.

Sets, reps and where it fits

Flies are an isolation movement for after the pressing or rowing is done. Pair a cable crossover with a cable rear delt fly on the same station, or dumbbell chest flies with dumbbell rear delt flies on the same bench.
