I am only in Scottsdale on a periodic basis. Have consistently seen large groups here so finally decided to try it out since I do boot camp and high intensity training elsewhere.
Did the sweat session with Sarah at 5AM for the first time. As a newby you get the first session free. It was truly awesome. First Sarah is a great encourager and very high energy. Second, compared to other places I have been the facility is a bit small. Then you realize that that's part of what makes it great. The crowd is definitely motivating but not judgey. I typically do a non stop 30 minute session so was bit concerned about the duration but the quick small breaks are just right. I will keep coming here as often as I am out.
Last note, really no shower facilities but the place has such good vibe it just doesn't matter.
Update, forgot to mention, Sarah is awesome as a trainer.
