Oh my goodness----I did my first "boot camp" class tonight. WOW-was it a work out. Actually, I don't think I have ever worked out that hard---and it feels great. It's a small class(tonight there were only 4) so it's basically like having a personal trainer. Have you ever seen the show Workout on Bravo? Those are the kinds of things we did. He switches you from cardio to muscle work about every 5-10 minutes. My arms are still shaking. He said I'll really be feeling it by Wednesday morning---just in time to go back again Wednesday night! They all promised me it gets easier. I had no idea how truly out of shape I am. What a wake up call!
