Founder Patrick Willard keeps the gym open to everyone and leads a team of nationally certified fitness experts to teach everything from Zumba to martial arts and yoga. Trainers motivate clients during small-group boot camps, swift 30-minute circuit-training classes, or one-on-one training sessions. Nutrition seminars supplement the sweating by preventing budding bodybuilders from undermining their gains by falling prey to unhealthy diets of cement sandwiches.
