As a newbie, I am so thrilled to be doing your workouts, Cathe, but having come from many years of doing the Firm, FitPrime, etc., I'm not sure what you mean by "circuit" and "interval." I'm guessing that other instructors use those words differently. Before, I always thought I was doing interval training (cardio plus weights) but it seems that that's what you call circuits. I could be totally wrong, but would you please explain the difference?
Thanks so much.
