20 Minute Anywhere Workout

My trainer has me sheduled for 45-60 minutes of cardio most days of the week.  Alot of time I only have enough time/ patience/energy for 20-30.  Most days I will go back for my remaining time.  Other days I will switch it out for a different type of cardio.  (A trip to the beach TOTALLY counts as cardio!)

I did this workout in the front yard.  I did my sprints and back pedals from one side of my yard to the other.  I have no clue what the actual distance is or how long it took me.  All I know is that I was out of breath from running hard.  Make sure it's a decent distance though.

This workout took about 20 minutes and I burned over 300 calories.
