CB routines are based on high intensity intervals mixed with toning recovery periods. CB is perfect for clients at any level, geared to burn calories and define muscles, improve your endurance and cardiovascular fitness, and shred your abs. Most of all, CARDIO BOXING IS FUN! Set to upbeat music, NY Fitness Lab will keep you from being bored by challenging your mind and your body. CB classes are a great complement to your more monotonous running or elliptical days. Not only can you burn as many as 500-1000 calories in a 1 hour class, but you will perform moves that tone your body unlike most cardio workouts do.
