Cycle Bike hurt me

mrsmojo82

I tried doing the bike for spin bike alone for 20 min to see if I could do the 45 min class. NO WAY!

I am not sure how to describe this...my muscles hurt. Not quite my groin muscles, but feels like its part of it. It's like in the crack where your leg meets your private.What did I do wrong? I liked how much I burned on the bike, but now I'm sore.
