I think it's a bad sign when you plateau with your workout regime only 3 weeks in. Actually, I'm just having issues with the aerobics. Denise Austin's strength training is still good for me, as evidenced today by my sore pectorals (or boobies if you want to get all technical about it) and bum. I am a weakling. Particularly my arms. I can't even do a couple of the exercises that are ostensibly for the abs because they require significant arm balancing and my arms aren't strong enough yet to hold all of me up for the time she requires.
However, I've passed the point where I feel like my heart rate is up high enough for long enough during the aerobics. To compensate I've been jogging in place during the commercials. And because the jogging in place feels good I find myself thinking crazy, CRAZY thoughts like "Huh, maybe I'd like running after all. I'd get to be outside too..." No, NO. Smack down those crazy thoughts, Kelly! I also realize jogging in place in NO WAY represents actual running and I tell my crazy brain this and she generally shuts up.
So any suggestions other than the aforementioned jogging in place to keep my heart rate up for longer? Actually Denise has some Tae Bo moves she does that I love and they usually get my heart pumping. Maybe I can just substitute those even when the routine for the day is the step-together with the arms swinging thing that she likes so much.
