You know you have a hard workout when you wish all sorts of evil on the instructor and look at the clock desperately hoping that time has run out just to discover that it's only been half an hour.

Also, there were several points where I mentally said, "oh, hellll no" and turned down the resistance on my bike.

Hahahaha. And I still had an amazing workout and completely deserve the huge pile of nachos that I had for lunch. That is why I love exercise.
