Forget the run-of-the-mill black yoga gear and suit up in a pair of sailor-style pants complete with paneled buttons. Stock up on flirty but inexpensive tees that can suit mommy's jog and Pilates class. When she needs to leave the sweat behind, she can throw on her Mary Jane Nike kicks and a comfy yoga wrap hoodie. Tame the post-workout hair frizz by pulling it back in a sassy headband. Mum will go from fit to fabulous in just enough time to say, "Carpool!"
