"Ghetto Westside" dumbbell band press - a trick I learned from HeavyBomber: String a stretchy-band (yes, one of those thin rubber hose things the ladies use in toning class at the rec centre) under the base of the bench you're using for dumbbell press - hold the ends in your hands with the dumbbells you're going to press; completely changes the dynamic of the movement.
**very helpful for those with RC problems, as the weight is at its lightest at the bottom of the lift.
