In relation to working out, what is a bench press, and how do you perform it?

The bench press is a weight training exercise targeting the chest and triceps. The trainee begins by lying down on a flat bench with a straight barbell directly on top of them. The trainee lifts the bar to extend directly above the head, and then slowly descends the bar until it touches their chest. The bar is then pressed upward until the arms are once again fully extended.
