What is pullover exercise good for?
Dumbbell pullovers can build upper body strength in your shoulders and back. The dumbbell pullover works muscle groups throughout your upper body, including your latissimus dorsi, your pectoralis major, the triceps on the back of your upper arms, and the serratus muscle on the side of your rib cage.
Are pullovers for back or chest?
Fitness experts conclude the dumbbell pullover works both the pecs and lats. However, you can only reap the full benefits for each muscle group depending on your form. When you position your arms and elbows in a certain way, you will target your pecs.
