work-out-nowNever mind the adorable girl showing off the exercise, but pay close attention to the instructions, here. I find that it took me a while to focus doing this exercise. You have to be careful that you’re not just swinging your legs back and forth, that you’re really working muscle groups with this one!

I started this one doing 10 of them back to back in three different sets. Give it a shot! Great for the booty, too!
