O2 Modern Fitness
O2 Modern Fitness helps clients of all fitness levels and walks of life reach their full fitness potential—including current mayor Jonathan Rothschild, who promotes physical fitness city-wide. With his days packed full of rich lunch meetings and countless hours at the desk, Rothschild spends his mornings pedaling away calories.
Now a tried-and-true fitness emporium, O2 Modern Fitness began when Susan Frank realized the key to keeping her genetically high cholesterol low: cycling. Today, helping clients achieve strength and conditioning through cycling (CYCL) and Cross Training (CROSS) are the primary goals of O2, thanks to self-paced group training. Yet beyond the bike, certified staff members lead students though high-intensity interval training that includes body-weight exercises plus the use of kettlebells and sandbags within the CROSS conditioning classes that heighten core strength and mobility.
