Named after the coach who popularized it, the Hyght fly adjusts the standard dumbbell fly arc so the weights finish up and over the upper chest instead of directly above the sternum. Load it like a regular dumbbell fly, well under pressing weight and controlled through the stretch, and use it when the flat version has gone stale.
How to do the Hyght Dumbbell Fly
- Lie flat on a bench with a dumbbell in each hand, palms facing each other.
- Extend your arms straight up over your chest, with a slight bend in your elbows.
- Keeping a slight bend in your elbows, lower the dumbbells out to the sides in a wide arc until you feel a stretch in your chest.
- Pause for a moment, then reverse the movement and bring the dumbbells back to the starting position.
- 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.
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.
