Seven-Day Wonder: A Week of Kick-ass Workouts from the Founders of FITiST

Neda Talebian Funk and Caroline Levy Limpert hate health-club monogamy—so they started FITiST, a site that allows members to mix and match classes from the best boutique fitness studios in NYC and L.A. and get customized plans from their roster of celebrity trainers (think David Kirsch and Jay Wright). The body-busting duo polled their experts and put together the one-week regimen.

Performance class—boot camp, interval training, or CrossFit
"This is a great way to kick-start your week—and your metabolism. Interval-training classes such as Barry's Bootcamp will push you outside your comfort zone—and will increase not only your stamina but also your speed and strength." —Funk

Indoor cycling class
"It's a great workout anytime, but we especially recommend spinning after a day of intense pounding on your joints or running. It is a low-impact cardio workout that we can't get enough of. In L.A., we love Cycle House, which just opened last fall." —Limpert

Performance class—boot camp, interval training, or CrossFit
"Wednesday may be hump day, but it's also the best day of the week to really push your metabolism with high-intensity interval training. In L.A., go to Brick CrossFit. Or, in NYC, check out As One or Velocity Sports Performance for a new take on functional fitness." —Limpert

Rest day
"Often underestimated, a rest day is very important. It not only gives you the energy for optimal training sessions on other days, but it also gives your muscles time to repair." —Funk

Fight session
"A fight class is the ultimate way to end the work week. You get out all your tension. Jumping rope is the best calorie burn out there, and your shoulders and core will feel the burn from all the sparring." —Limpert

Indoor cycling class redux—or a run
"Hate indoor cycling? Go for a run outdoors instead. In our minds, there is nothing better for clearing your head, so grab your iPod and run off the week's stress!" —Funk

"Yoga complements the rest of our hard-core program with needed stretching and an emphasis on inner peace. It's also a great way to sweat out Saturday night."—Funk
