Firemedic, I love that Cardio Core Circuit. It's just fun, fun, and hard. I always forget how aerobic it is until I do it again. Hope you have a restful day.
Jodi, I did that same workout yesterday, abs and all. I thought X10 step was harder than the Plyo 2, but that one is always moderate for the stepping, but super hard at the end with the weights - totally sucking wind.
I'm scheduled to do LIHI Chest, but woke up dog tire and have no idea why. I'm going to start it and see what happens. Hopefully I'll get some energy once I get going; that happens most of the time.
