what muscles do overhead press work

The overhead press is a compound exercise that targets multiple muscle groups in the upper body. The primary muscles worked during the overhead press are the deltoids, triceps, and traps. Other muscles that are worked during the exercise include the pecs, serratus anterior, abs, and upper back muscles such as the trapezius and the serratus anterior. The overhead press can be performed in a seated or standing position, with a barbell or dumbbells, but using a barbell makes the lift sturdier and allows you to lift more weight and engage more overall muscle mass. The overhead press can increase the strength and size of the shoulder muscles, triceps muscles, and trapezius muscle, as well as the strength in the core muscles such as obliques, transverse abdominal muscles, lower back, and spinal stabilizers.
