I needed something different today and was too exhausted to go through the motions of getting myself to the gym. So, instead, I did this HIIT video. It kicked my butt in a great way! I was dripping sweat and it was refreshing to know that the instructor was having just as hard of a time. Christine Salus has a great personality and will keep you motivated to keep on.
