Today's Workout~Nov 5th 2013

Today's workout was rather nice.I was expecting it to be sluggish,it was a nice even paced run with a little HIIT added in there for variety.Each workout is something that I look forward to and I get something different out of it each time.What workouts do you do?Do you change yours up?Do you add a little extra speed or that extra rep?What do you get out of each workout?For me I work out to build endurance and to stay healthy.I also workout too to keep my weight in check.
