Rotation?

[kerribilliot1]

I have previewed most of the new DVDs. I am used to doing cardio 3 days and weights 3 days/week. So many of these workouts seem to be more of a circuit style. I understand that to build muscle you need to lift heavy, not light with numerous reps. My question is how do I incorporate heavier weight training in with these circuit style workouts?Or can you build adequate lean muscle mass only doing circuit workouts?

Excellent question. I hope Cathe sees it and responds....

Cathe posted that she would be posting a rotation on Monday (I think). I have also been wondering how to rotate these. I love all of them and want to know how to use them. Thanks so much Cathe!
