Circuit Training

Today at the gym I did something new.  Circuit training.  My gym has an area set up for this which made it easy.  Basically there are weight machines as well as steppers.  There's a light that displays red or green.  Each light is 30 seconds long.  While the light is green you do the activity, when the light is red you move to the next area alternating the steppers and weight machines.  I have to say that it was a nice switch from the regular workouts that I do.  I will definitely be throwing it in my routine.  The whole workout is 30 minutes, so it's really nice on the days I'm running short on time.  Today I began the day with 15 minutes on the bike and ended with 12 minutes walking on the treadmill.
