This is a phrase I hear constantly while doing my workouts. In the beginning, it really drove me crazy. I would yell "SHUT UP!" every time I heard it. I couldn't even tell where my abs were, let alone whether or not I was holding them in tight. I would just suck in and hope that something was happening. Now, entering my 7th week of doing these workouts, I can not only tell that I have ab muscles, they also feel tight the entire time I am doing the workout. That makes me feel pretty darn good. For the record, I have lost 2 1/2 inches off my waist so far. The same from my hips. I've also lost another half inch from my arms and thighs. I'm feeling pretty happy.
