The biggest fitness trend of 2013, high intensity interval training, is showing no signs of fading, and Brooklyn CrossFit has this style of workout down pat. The owners of the successful Brooklyn CrossFit: Columbia Street have expanded their empire to a new, larger location on the Williamsburg waterfront called Brooklyn CrossFit: South Williamsburg. Inside this nearly 2,000-square-foot space, you can work out with a personal trainer or take group or foundations classes limited to just 12 “athletes,” their very positive term for members who practice a high intensity, yet scalable fitness regimen that includes Olympic weightlifting, endurance, gymnastics, and calisthenics. The friendly workout environment at both Brooklyn CrossFit locations is designed to keep you motivated, as you learn a new “Workout of the Day” with coaches who foster community among your fellow athletes and overall health and fitness. Classes are available at multiple package levels and discounts are available for civil servants, military personnel, couples and athletes who purchase an extended time package; you can even test out Brooklyn CrossFit with a free intro class.
