Barry’s is the original high-energy, calorie scorching, cardio and strength interval training workout that kicked off a boutique fitness movement. Founded in 1998, the signature Barry’s method has remained the same for over 21 years because it works: a 50-60 minute class can burn up to 1,000 calories, increase lean body mass, and raise metabolic rate up to 15%. The workout is designed to push you to your physical and mental limits.
