Main muscles working (thicker lines)
Lie on a flat bench with feet planted and shoulder blades pinched, gripping the bar about three inches wider than shoulder width on each side.
Unrack the bar and hold it over your shoulders with arms locked.
Lower it slowly to the middle of your chest.
Touch lightly without bouncing.
Press the bar back up to lockout, squeezing the chest.
Breathing: Inhale as you lower, exhale as you press.
Forearms vertical at the bottom
Shoulder blades stay pinned
Squeeze the chest at the top
Going so wide the shoulders ache
Flaring the elbows straight out at 90 degrees
Bouncing the bar off the chest
Stay close to the bar's ring marks unless you are used to wide pressing; very wide grips stress the shoulders.
Use a spotter or safety arms when training heavy.
