Lindsay Brin: HIIT Cardio - High Intensity Interval Training

Did this workout this morning-Lindsay Brin: HIIT Cardio - High Intensity Interval Training. It was short and sweet so I was able to squeeze it in after working all night and before the baby woke up from her brief nap. Good thing too 'cause it's hot out there. It was great to feel like I was doing some speedwork too.
