Thursday, April 30, 2009 ... cardio day ... I t was a cardio only day and I did 30 minutes on the elliptical machine accept part way through my stomach was off. I had to push through it. I wonder if it was a result of not having enough liquids in me. Not sure. I was in no shape afterwards to do stomach crunches. Since I haven't been doing as many leg lunges and leg squats, I could feel it today. My thighs were tight. Probably should have done some stretching, but I just wanted to leave.
