Purpose of Exercise: To build the mass of the upper pectorals.
Execution:
These flys are done the same as normal flys except you lie on an incline bench and your head is higher than your hips. Lie on a bench with the dumbbells held straight overhead, palms facing each other. Lower the dumbbells out and down in an arc, keeping the palms facing each other and a slight bend at the elbows. Lower the weights until the pectorals are fully stretched. Come back up through that same wide arc as if giving a big hug. At the top squeeze the pectorals to ensure contraction.
Insider's Tip: Do not press the weight, let the pectorals bear the weight and bring them up.
