How to perform
Lie flat with dumbbells held above your chest, palms facing each other.
Keep a soft, fixed bend in your elbows throughout the movement.
Open your arms out to the sides in a wide arc until you feel a stretch across the chest.
Bring them back together along the same arc, thinking about squeezing your chest rather than pushing with your arms.
Use a weight you can control. This is a stretch exercise, not a pressing exercise.
Common mistakes: bending and straightening the elbows, which turns it into a press, and going far too heavy.
