Well, I offically started my Tae Bo workouts today, and I guess it's obvious it didn't kill me (yet). I didn't make it through the whole tape, and I only did half of the sets they did, but I broke a pretty good sweat, and called it quits when I knew I had enough. Not too bad for one who hasn't worked out in about 20 years or so. I did enjoy the workout, and I feel it will keep my interest for a long time. I plan to do basic mat exercises along with the Tae Bo as a change of pace. Phew............gotta hit the shower.
