Too darn hot!

I did my first spin class yesterday. All in all I don’t feel too wrecked today. It was not what I expected. I thought my main issue would be keeping up with everyone, and pushing myself to the limit. The problem was heat, it was almost unbearable in the room. I hate to cycle when temperatures rise above 85 degrees, so I thought a spin class would be a cooler, indoor alternative. I went though a little bit of heat shock when I got home last night and now I'm a little annoyed as my master plan to maintain fitness had a big bubble burst yesterday. I am unsure whether I will take another spin class.
