I am not a huge fan of cardio and would prefer to just  lift weights faster.  Unfortunately, I have a specified amount of cardio in my weekly plan that I must do to reach my goals.  It’s cold here in Michigan so I decided to stay indoors and hit the treadmill for some intervals.  On paper this workout looked pretty manageable but let me tell you, I was dying half way through  (I did this the day after leg day so that probably didn’t help).  I may have had to walk during a few of the recoveries but I pushed through all of the sprints until the end.  After completing the below intervals I named it “Butt Kicking Treadmill Workout”.  Have fun and enjoy!
