Linda Lu's Fitness, West Chester

Having amassed almost 30 years' worth of fitness expertise, Linda Mitchell doesn't believe in age as a limiting factor. The AFAA-certified personal trainer, Ms. Fitness USA competitor, and regular contributor to Ms. Fitness magazine teaches clients how to woman-handle their exercise goals regardless of their backgrounds. She founded ChickFit as a studio where women could work out among friends and nonintimidating teachers. There, her signature sessions—which range from boot-camp classes to cardio-kickboxing rounds—tone physiques, tap into wellsprings of confidence, and ready bodies for beach season. She weaves a common thread of compassion and skill through heated yoga sessions, jogging seminars, and dance-fueled aerobics classes, encouraging guests to "embrace their age" as they bypass fitness milestones, such as pole-vaulting through a ring aflame with birthday candles.
