I arrive at the place dressed in comfortable shoes and clothes. I was not comforted by my instructor who said she lost 18 lbs 4 years ago. Bah. You don't know what kind of Hell we live in. But she was nice enough. Two times around the circuit, bouncing on a recovery pad between each hydraulic machine...not bad. My heart rate was over the recommended count for my age and exertion level. I didn't stroke out, though. I left in a much better frame of mind that I have been in for about two weeks. I would say that is worth the price of admission alone to my dear husband!
