Comments and tips

  • Invented by Dr. Clay Hyght, the Hyght dumbbell fly is an excellent exercise for building the upper chest.
  • The Hyght dumbbell fly was designed to simultaneously work two of the primary actions of your upper pectoralis muscle: flexion (raising your arms up) and adduction (bringing your dumbbells together).
  • Dr. Clay Hyght suggests that you think of forming a triangle with the path of the dumbbells, with the tip of the triangle over your nose.
  • Start with a light set of dumbbells.
  • Make sure that you are pressing with your chest muscles, not your shoulder or biceps.

Hyght dumbbell fly video

The demonstrator in this video fails to make a V shape with the dumbbells as he brings them up and in across his body. This is because he rotates his forearms as he lifts the dumbbells up. Make sure that you keep your palms facing up as much as possible throughout the exercise.
