To perform a bench press, lie flat on your back on a bench with your feet flat on the floor. Grip the barbell wider than shoulder-width apart. Your forearms should be vertical when the barbell is in the bottom position. Lower the barbell to your chest, keeping your elbows at a 45-degree angle to your body. Push evenly through both hands to return the barbell to the starting position without locking out your elbows. Perform three sets of eight to 12 repetitions.

Grip the barbell with your hands slightly wider than shoulder-width apart. Pull the barbell to your torso, keeping your elbows close to your body and avoiding shrugging your shoulders. Slowly lower the barbell back to the starting position. Perform three sets of eight to 12 repetitions.
