What Have You Done Today to Make You Feel Proud? What Kind of a Loser Are You?

I totally understand preserving your knees at ALL costs.  I used to do TaeBo at 275 pounds...what the hell was I thinking?  The fast movement was starting to affect my knees so I quit immediately.  Now I do the moves, but modified to be slower and more intense, and I do something else for cardio.  After seeing my sister suffer through knee replacement weighing over three hundred pounds, I don't even want to think about going there!
