The upper-body exercise described is the bench press: you lie on a bench and press a barbell upward from your chest. It is one of the best-known strength exercises for developing pressing power in the upper body.
In a conventional barbell bench press, the lifter lies on a flat bench, grips the bar slightly wider than shoulder-width, lowers it toward the chest, and presses it back to arm’s length. The pectoralis major, triceps, and front portion of the deltoids all contribute to the movement, while the upper back and legs help stabilize the body.
The incline press is a variation performed with the bench angled upward. It generally places more emphasis on the upper chest and front shoulders. A shoulder press is different because the weight is pressed overhead, usually while sitting or standing. A push-up follows a similar pressing pattern but uses body weight and a fixed floor position instead of a barbell.
Because the bench press involves heavy loads, a stable setup, controlled repetitions, and an appropriate spotter are important. Competitive powerlifting usually uses a flat barbell bench press as one of its three main lifts.
