Legs and Butt...

I like easy and I like not having to get on the floor!  I know your stability/balance ball is out because you are using it!  Here is a new exercise…

Lie face down with your hips centered on a stability ball and hands on the ground in front of you, elbows slightly bent. Bend knees and press soles of feet together.

Lift legs until thighs are parallel to the ground. Lower legs and repeat.

Thank you Shape Magazine for another good one!
