Begin with weights that are light enough for you perform the exercise properly, but heavy enough for you to have total muscle activation. At the bottom of the rep, begin with your armpit angled out at about 45 degrees away from your torso. Push the weight up, extending but not completely locking out the elbows and keeping tension on the upper pectorals throughout the rep.
- Avoid too much shoulder use.
- Do not flare your elbows out wide
- Imagine holding something the size of a grapefruit in your armpit while performing the exercise.
