Let's take a minute to talk about this new exercise class I've been taking. By "I've been taking", I mean I've gone to exactly 4 classes. It's called PureBarre, and it kicks my hiney. I mean my seat. Have you done PureBarre?
The whole point that you push each muscle group to the point of fatigue. You basically want every part of your body to shake. Sometimes (Read: all the times) that means I jiggle and wiggle as I walk out. Because my limbs don't know what to do with themselves while my muscles are dead to the world.
