Enlisting in one of these bridal boot camps is a great way to jump-start your pre-wedding fitness regime.

What To Expect: 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 with 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 guildelines, 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.

Logistics: $400 per month for three workouts a week, or $600 for five workouts a week.
