A day after working with the Personal Trainer, I am having a "get-to-know-you" session with my abdominal muscles! I tried to convince the PT that I did not think I had any ab muscles, and if I did, they were not working well AT. ALL.! She has proven me wrong again, and the intense, almost painful sensations in my midsection are FABULOUS!! This thrills me, and lets me believe that having a toned, highly-functional midsection is possible! Whoo-hoo!!
