For example, there is a Triathlete Corner for “Ironmen,” and a Hypoxic Room challenges people who like to simulate workouts at oxygen-challenged levels. Intriguing group workout sessions include Aerobics With Attitude and Israeli Boot Camp, but Crunch also offers the customary conditioning classes (aerobics, step, abdominal workouts, body sculpting). Apparel and accessories are also available.There are a number of other Manhattan locations, including near Union Square and on Houston Street and Lafayette Street.
