That's really good to know, it gives me an idea of what to expect. I'm glad you are getting really good definition. I agree with you as far as the beauty of this workout being the fact that you can modify it to your liking. I'll have to check in with you and see how you do through the second go around. I have only finished my first week and my core feels very tight and strong and it's only my first week. That may be my imagination, but it certainly feels that way. Thanks for the information.
