I just discovered that my Comcast On-Demand has workout videos! I did a session with Bob Harper from the Cardio Max DVD...it was pretty darn awesome. Also did some tai chi-ish stuff, since I've always been interested--even that worked up a little sweat, and it was a nice contrast to the more vigorous exercise.

If all of Bob's stuff is that fun, I just might invest in the DVD...I like that I can try before I buy, though. *grin*
