The incline bench press primarily works the upper portion of the pectoral muscles (upper chest), along with the anterior deltoids (front shoulders) and triceps (arms). Setting the bench at an incline of about 15 to 30 degrees shifts the focus from the middle and lower chest (targeted by flat and decline presses) to the upper chest, helping develop a well-rounded and sculpted chest

. Key points about what the incline bench press works:

• Upper Pectoral Muscles: It isolates and activates the upper chest more effectively than flat or decline bench presses, promoting muscle growth and strength in this area

• Shoulders (Deltoids): The incline angle engages the anterior deltoids more, contributing to shoulder strength and stability

• Triceps: The arms also work to extend the elbows during the press, involving the triceps muscles

• Range of Motion and Muscle Activation: The incline bench press involves a longer bar path than flat or decline presses, increasing muscle fiber engagement, especially in the stretched position of the upper chest

The incline bench press is also considered safer for the rotator cuff compared to flat bench pressing, reducing stress on this common injury area

. Proper bench angle (around 30 degrees) and technique are important to maximize upper chest activation and avoid overuse of the front deltoids

. In summary, the incline bench press is a muscle-strengthening exercise that targets the upper chest, shoulders, and triceps, helping to build upper body strength and a balanced chest appearance
