Celebs like Kim Kardashian, Amanda Seyfried, Jessica Biel, Katie Holmes, and Jake Gyllenhaal flock to Barry's Bootcamp to get a killer workout in a fun, party-like atmosphere. But if the class dubbed "Hollywood's secret weapon" hasn't made it to your hometown yet, you can still burn serious calories at home with Barry’s Bootcamp Extreme: 1000 Calorie Workout DVD ($9.99; barrysbootcamp.com).
What to expect: A challenging 45-minute workout that combines 10 of Barry's favorite fat-blasters. You'll do 100 reps of each exercise, but Barry keeps you inspired and entertained while you chase the burn.
You'll need: Resistance bands and a workout bench (a box or step will do).
