Party on a Bike was hands down the best spin class I've ever attended. The instructors were awesome. Out of the 3 that I tried, I would say Lindsey Reuben was the best. She was upbeat (the lights also helped) and it was a themed class (Eminem vs. Kanye) and at one point she walked around the room and started rapping. Overall, she kept it exciting and I didn't even realize the hour had gone by. You definitely get an intense workout and just SWEAT. The only downside is that it doesn't have childcare and parking is slim. Otherwise, drop in and take a class!
