I absolutely love circuits. When I think of circuits, I think of workouts like Cardio & Weights, where you are switching back and forth between cardio and, well, weights. I think they are a lot of fun and the workouts just fly by. Circuits are really more for endurance (I think), than for strength or hypertrophy, and for changing things up, rather than for any long term rotation. I think circuits are much more difficult than cardio or weights alone. I usually try do at least one circuit a week!
