Gym Bunny

I have gone to 3 classes this week already...Monday really kicked my butt and still hurts to laugh, or cough. Tuesday night my other Bunny had me try Kick Boxing..Well I basically thought I looked like a fool, and I was seriously embarassed. But I made it through even with Dan and Conley laughing at me, and later Conley telling me I looked like a freaking retard...Wednesday I went to the class they recommend BEFORE you take the class I took on Monday, so it was way easy for me, and didn't even sweat. Tonight I am trying to make it to the 530 class for Strength. I am still sore, but it feels good. I like the teachers at Lifetime because they are nice, and they introduce themselves to you. Any advice on why I gain weight when I start working out really hard? That really pisses me off!!!
