There are a lot of myths floating around about weight loss. The fact is that some people don't ever experience plateaus, so why worry about this ahead of time?
My own experience, having been on a plateau for a few months now, is that it doesn't matter what exercise you are doing or not doing. I have been going to the gym 5-6 days a week for the last month, doing different things every day I'm there, and it has made no difference yet in my plateau.
Good luck! Keep going! I love my Tae Bo tapes, although I don't do them so much these days. Hmmm
