The Dumbbell Pullover is a compound exercise that primarily targets the chest and latissimus dorsi muscles in your back. Performed with a single dumbbell, this exercise involves lying on a bench and pulling a weight over your head to stretch and contract the targeted muscles. Dumbbell Pullovers can improve upper body strength, posture, and contribute to a broader chest and V-shaped back. Variations can include different bench angles or using a barbell instead of a dumbbell. To get the most out of this exercise and minimize the risk of injury, it's crucial to use controlled movements and proper form.
