Barry's Bootcamp has an incredible reputation for drawing celebrities and fitness fanatics through its doors in major cities worldwide. They vow students will burn up to 1,000 calories per class! When living in the Big Apple I would workout quite frequently at Barry's Bootcamp. I started going regularly while getting ready for my Central Park wedding! My favorite time to go? Thursday afternoons at the Chelsea location. Each day trainers run students through workouts targeting a specific muscle group. Thursday is abs day. I found their formulas to be challenging but manageable. 'Barry's' - as its fans like me refer to it - now has more than 25 worldwide locations including Los Angeles, New York City, Chicago, London, and Oslo. It was founded in 1998. Reps tell me today... more than 40,000 people visit their fitness studios every week.
