I was the chubby girl growing up...like, C-H-U-B-B-Y. So, an exercise better bring a lot to the table when trying to get the attention of a girl who loses all focus once cake enters a room. I fell in love with CYC after attending Yelp's In It To Thin It event (http://www.yelp.com/biz/yelps-in-it-to-thin-it-cyc-fitness-madison#hrid:1qfbFKHfrY26SfAHv2_GlQ/src:self) and I've gone back for more through their current Summer 6-Pack promotion.
I've been back twice, once at 6:30pm and again at 12:30pm. Hit up a 12:30pm slot if you're looking for a class that's a little less packed (at least through the summer while students are gone) but still high on energy. The pricing is a wee bit high but it seems like they dish out various specials and package deals fairly frequently, which makes it more reasonable. The staff is fab and the "cycologists" show no mercy as evident in the sweat-drenched clothes I usually walk out of the studio with.
After 45 minutes I leave and am all, "Cake? Cake who?" It's a good thing.
