Sit in the seated dip press machine.
Use the entire weight of your body to press down the machine lever.
Press your shoulder blades downward and backwards together. Hold this position tightly during the entire exercise.
Keeping your core tightly squeezed, allow your elbows to bend while staying snug to the side.
As your elbow raises maintain the squeeze in your belly and shoulder blades. When they can not hold the original position or reach a 90* angle, stop.
Pause 1-2" then press your palms down towards the ground, straightening the arms.
Squeeze the triceps tightly while re-squeezing the shoulder blades together 1-3".
Bend elbows slowly and repeat repetitions to failure.
