Fat or Fit--Worth the money?

Yesterday I worked with a personal trainer for the first time. I am sore today, but it's a good feeling. I just hope I can move tomorrow! I decided that I am willing to pay for someone to get me off my rear and get some muscle tone back in this body. I will voluntarily ride my bike or go for a run without needing outside motivation, but I lack the self-motivation it takes me to lift weights, do push-ups and sit-ups--they make me sore and I'm just not that pushed to do it on my own. Therefore, I'll pony up the money for someone else to give me encouragement to make myself stronger and toned. Plus, I may just lose all this extra weight I've got hanging around!
