What muscles do bench presses work and how can I effectively target them during my workout routine?

Bench presses primarily work the chest muscles (pectoralis major and minor), as well as the triceps and shoulders. To effectively target these muscles during your workout routine, focus on proper form, gradually increase weight, and incorporate variations such as incline or decline bench presses. Additionally, incorporating accessory exercises like push-ups, dips, and shoulder presses can help strengthen and target these muscle groups.
