I heard about the workouts from a girlfriend. She and her boyfriend take classes at least twice a week. They love the workouts but did state you must sign up early because most of the time, classes fill up very fast.
I was looking at the schedule in Chicago and I'm interested in taking the NTC HIT and NTC Barre 30 classes.
NTC HIT: Join us for a 45-minute Nike+ Training Club (NTC) workout. NTC is a sport-inspired, full body workout designed for all fitness levels. Guided by an expert trainer, you'll squat, lunge, and move your way through this metabolic workout, alternating between period of low- and high-intensity.
NTC Barre 30: Go from work to workout with this 30-minute NTC Barre session designed to let you strengthen, lengthen and tone your muscles on your lunch break. Train smarter, not harder. Join us for NTC Barre 30 and squeeze your workout in for the day. Source: Niketown
I don't know when they open the sign up list but I heard it is at 2:00pm the day before the class is given. I think I will give it a try real soon.
Do you live in one of the above cities? Have you tried workouts at Niketown?
