Get your rear end in gear without the years of ballet training the girls in "Black Swan" underwent. I've spent just two weeks using the Bar Method's Beginner DVD and already my thighs are more toned and my tummy is flatter. The exercises are easy to perform (while still being challenging) and the 38-minute workout makes you sweat without destroying you.
As a bonus, if you're an apartment resident it's a great DVD to do at home. There's no loud jumping that may upset neighbors.
If you're here in Chicago you can also try out a live Bar Method Class.
I can't promise you you'll transform into Natalie Portman--but it's a fun workout that offers quick results.
