dumbbell pullover to ball crunch.

this move will work your core, targeting your upper abdominals, and your upper back.

start by laying with your back on a stability ball and a dumbbell in your hands, griping each end.

hold the dumbbell in the air and make sure you are holding your hips straight and flexing your glutes and core.

reach back as far as you can with the dumbbell, make sure you feel a nice stretch in your upper back.

bring the dumbbell back up as you roll into a ball crunch.

hold the dumbbell in close to your chest as you complete a ball crunch.

repeat! 

i like to do 3 sets of 15 reps.
