Stretching

Can stretching before class hurt your dancing? New science suggests it might. Yesterday, I  listened to a recent interview on NPR’s Fresh Air program with The New York Times Phys Ed columnist Gretchen Reynolds, who just came out with a book called The First 20 Minutes. Reynolds explained that almost all research now suggests that stretching prior to working out is counterproductive: It causes your brain to think you're going tear the muscles.
