I was visiting Scottsdale over the weekend & wanted some exercise but couldn't handle the heat outside. I took the 45 minute class on Saturday morning & it was perfect - definitely challenging but only took 45 minutes to get a full body workout. They have really great art on the walls too so for those of us who don't like to look at ourselves in the mirror - some good landscape eye candy! They also have cute little smiley face stickers on the equipment - their main purpose is to show you how far to bring the carriage in but they're also little personal cheerleaders if you're feeling particularly challenged! Rebecca is such a sweetheart - served green juice for us all. Will definitely be back on my next trip to Scottsdale.
