Back to Spin Class

I have not been to a spin class in so long. I had to hunt down my shoes the night before. arrived at class late and stumbled with all the knobs. I was all set with my new HR monitor and averaged about 140. Class is only 45 minutes (or 38 when you arrive late). i made myself stay after until I finished the entire 60 minutes. Ok, today I am a little sore. But it's Thursday...meaning I get the day off.
