Standing at a cool 5'2 and weighing a mean 120lbs I'm not exactly the one you'd fear if you ran into me in a dark alley. (In fact, I'd probablly be the one to turn and run away.) But when it comes to my workouts I've found that traditional aerobics classes are not what I need nor enjoy.
Ex-rugby player turned cream puff I am the type of city girl who loves to sweat and feel the burn days after my workout is done. I came in with absolutely no training whatsoever but their trainers and classes had me feeling like a pro in almost no time at all.
You don't even have to buy your own gloves but I do recommend it, especially if you are on the dating scene. ; )
the gym offers a wide range of opportunities to box-yer-butt back into shape while having an absolute blast.
