The Screamer Lunge exercise works your butt and legs.
-Alright, it??s called screamer lunges. It??s a great way to work the thighs and the butt. Get on down there, Emily. She??s in a low runner stance. See the 90-degree angle to both legs? Perfect. Bring up that right leg in the air. Emily, in again. She??ll do 5. I like you to do 30 on each side. How about that? Left and right. Nice job. Killed it.
