"I carry a FEED bag. They're light, easy to wash and benefit many great charities."

"Julie and I received personalized Goyards as a gift. They're amazing. Lightweight, beautiful, chic. The best for travel and the gym."

"I wear cycling tights with either skulls or wheels screened on the leg, a sports bra, cotton tee or tank (usually by Free City or Aviator Nation) and always a wrist band."

"I'm totally into the Falke bra and usually do either a Nike or Lululemon tight with a SoulCycle shirt. It has to perform and feel great."

"Lancome Flash Bronzer adds great natural color so I don't need to wear anything else on my face. For my hair, Kerastase Oleo-Relax controls the waves and makes it easy to do a slicked-back bun post-class. My silver Adidas high tops are comfortable yet a little flashy. And almonds are a healthy, easy-to-carry snack."

"I'm big on the 'French bath' until I can shower, so I carry Santa Maria Novella orange water perfume. Also, Fiberwig mascara which doesn't run. It's important not to get a chill, so I pack SoulCycle sweats to wear post workout. And water — hydrate, hydrate!"

Julie Rice and Elizabeth Cutler are as cool as cult leaders get. Since starting SoulCycle in 2005, snagging a seat in some of their NYC and LA spin classes has become as coveted as reservations at Momofuku Ko. You can't mop a brow without hitting a celebrity. And there is an entire subculture of the sweat-obsessed that lock their office doors on Monday mornings, refreshing browsers until that week's bikes have been booked. It's a fever. Rice and Cutler are busy expanding their brand (five new locations will open by the end of the year), and, yes, you can sometimes find them sweating outside their studios. "When I'm not at SoulCycle, I like to work out outside," says Rice. "I lead myself on a mini boot camp along the west side highway — the fresh air and scenery help clear my head." Cutler, for her part, does yoga, barre and swim. "I was a big yogi before starting SoulCycle." Here, they offer a glimpse inside their often-used, very cool gym bags:
