Same spin class, conducted by different instructors, will reap different results.

I'm really liking the Fri spin class. No matter how tired I feel, I just feel better after that. That's the one class that I felt my legs aching after the class. He just really push you. HARD. He would come up to your bike and tell you to spin faster, that what you are doing is not good enough. Slackers stay away.

Good class.

And yet there are other classes where I just drift away in the midst of it all. I would be thinking about work, about other stuff (like what to eat? :P). That's the one symptom that the class isn't motivating. Sadly, I noticed one class that I used to enjoy, falling into this category lately.

Ok ... weekends coming! Can't wait!
