The bench press is a popular exercise that works your chest, shoulders and triceps. Here is an ultra short step by step guide for doing a bench press with a bareball wide-grip:
Lie down on a flat bench and grasp the barbell with your hands slightly wider than shoulder-width apart.
Lift the bar off the rack and hold it above your chest with your arms fully extended.
Lower the bar to your chest in a controlled manner, keeping your elbows tucked in and your wrists straight.
Press the bar back up to the starting position, exhaling as you do so.
