Dumbbell pullovers are a bodybuilder's secret to great pecs, but they also work the lats and serratus anterior. This version uses a vertical bench.
If you can do overhead presses and pull ups or lat pulldowns, then the shoulders should be fine for this exercise. If you have shoulder issues, take precautions.
Stretch as deep as you can, exhaling as the weight moves behind the head. Throw this on as accessory work at the end of your routine, working in a higher rep range.
Ready to take things up a step? Try this version which allows for a deeper overhead reach. Bonus glute work from a glute isometric squeeze is always a plus when it comes to any exercise.
