Dumbbell pullover tip

The dumbbell pullover is great movement to incorporate your lats, pecs, and core, but if you are really looking for a way to target the lats, try it sitting backwards on the preacher curl bench

Set the pad at height that hits your mid to upper back, this will allow you to take your core out of the equation and get a better stretch in your lats. — This is also a great way to introduce the movement to beginners who may not have the core strength/balance to lay across a bench the way you normally would for the pullover
