Love the energy, that every workout is different and the music rocks! Both Darren and Evi are great coaches that get the energy level started off perfectly! Haven't taken anyone else's classes but I'm sure it's pretty across the board :) Highly recommend!
I have been very impressed with the quality of the instructors, as well as the intensity of the workouts. This type of training isn't right for everyone, so I am a little less likely to recommend it. It is not because of a problem with the studio or staff.
By the way...don't be so tight with the wipes. Your staff should be encouraging cleanliness, not asking people to use the same wipe through the entire session.
