A bench press is an exercise that can be used to strengthen the muscles of the upper body, including the pectorals, arms, and shoulders. Depending on your goals, there are different variations of bench presses that work slightly different muscles, too. For example, a narrower grip bench press will put extra emphasis on the triceps and forearms. Other benefits of adding bench presses to your weight-training regimen include increasing upper body strength, improving muscular endurance, and even preparing your upper body to do movements like pushups. They also can be an effective strengthening exercise for sports like sprinting, hockey, and football.
