Red room of pain

So while on medical leave after surgery I read the series "fifty shades of grey". Just recently I read it a second time. In the books the main character Christian Grey has a red room of pain where he does "interesting" things to his submissives. Well today I started personal training. Had to sign paperwork and talked about what I wanted from this besides weight loss. I said, endurance. So she said ok well let's get started. We'll start in the red room. Immediately I thought, red room of pain and about curled over in laughter! And let me tell you. It might not be Christian Grey's red room of pain but it inflicted its own sort of pain!
So yes I'm starting a personal training program. She helps come up with exercises to do and since I have a gym at work I will then go there and proceed with what she has instructed me to do. Then every couple weeks go back and come up with a new program! I'm excited to do this! Although my legs feel like jelly right now, but the more I do, the easier it will be and more I can push myself! I want endurance. I want to be active and run around and have fun!
