HOW: Lie back on a bench with your feet ideally on the ground. Brace your stomach and drive your heels into the ground, then push the dumbbells up into the air. Lower your arms back to the starting position, and then repeat. Your arms can be angled 45 degrees from your torso, or however you prefer.
FEEL: This should feel like an upper body workout, your arms and chest will feel like they are working.
COMPENSATION: Do not loose pressure in your abdomen when you are pushing the dumbbells overhead. At the top of the press the weights/objects should be positioned over your shoulders. Do not excessively flare your elbows. Stay strong through your wrists keeping your knuckles facing the ceiling.
