1-Lie down on your back on an incline bench and holding a dumbbell in each hand at the top of your chest, palms out. The incline of the bench can vary depending on what part of the upper chest you want to focus on. Standard is 45 degrees we do it at 60 degrees.
2-Push the dumbbells straight up straightening your elbows but not locking them. Squeeze muscles when contracting making sure the weights do not hit each other. Then return to starting position and repeat.
