it is called physique 57, located in beverly hills, and is supposedly how kelly ripa got her toned body (she probably also doesnt eat, but that's just a small detail).
it is basically like the bar method or pure barre, but on crack. there were actually men in the class! it was really fast paced, with 2 different instructors yelling out the moves and coming by to check form. it was non-stop- absolutely not one moment for boredom. the hour (oops, 57 minutes), starts with a weight workout, in which i was in sweating in no time, and then continues to the bar.
i was sore later on that day (and THOUGHT i was pretty in-shape). it is now 2 days later and i am still sore (proof of an awesome workout.) if you live in ny or la, you should try it!!
ps- they give you a free tape measure so you can track how much your body has changed= fab!
