Triceps, Pecs and Shoulders... Oh My!

I forced myself to go to BodyPump over my lunch hour yesterday. I lifted about two pieces of paper and a toothpick for most of the exercises with the enthusiasm of a drugged rat. Yet somehow I still woke up this morning a little sore. I managed to gain back that two pounds I lost, too. I guess the new phrase is, "Some pain, some gain."
