Are pullovers good for chest?
The pullover was a favorite move of some of the greatest athletes of the Golden Era of bodybuilding including The Oak, Reg Park and Franco Columbu. This exercise works not only the chest but also the lats, intercostals and serratus anterior (the muscles of the ribcage).
Do pullovers work upper chest?
Dumbbell pullover is one of the best isolation exercises to target the upper chest muscles and give you a fully developed chest. Though it takes time to perfect the Dumbbell Pullover movement but once you are accustomed to it, you will be able to blast off the upper chest fibers.
