Joining is like having a membership to every top boutique gym in town. Each plan lets you mix-and-match classes at its carefully vetted studios, and booking is completely hassle-free. The well-rounded Bride program includes eight cycle, four core, four performance, and two yoga classes per month. Not into spinning? Select another program, or have one customized for your specific goals.
Celebrity trainer Terri Walsh's workouts are based on Active Resistance Training—a tough-as-nails circuit of constantly changing exercises that use your own body weight (and the occasional kettle bell), challenge stability, and keep your heart rate up. After a private consultation, Walsh will prescribe three or five sessions a week for a month, then help you zero in on specific body parts during those workouts. Classes are limited to 10 to 12 people, so you're sure to get plenty of attention—which means no cheating! After camp officially ends, enlistees get an A.R.T. Method app, nutritional guidelines, and membership in a private Facebook group for added motivation and surprise video challenges. Plus, Walsh and her team are available 24/7 via email and text to tweak your meals, offer new exercises, and keep you in the groove.

Like all stays at Red Mountain, it includes accommodations, three spa meals a day, all group-fitness classes and hikes, and use of the sun-splashed Sagestone Spa.
