Jeff Lewis
Jeff, the driving force behind Jeff's Gym, is a passionate advocate for transforming lives through fitness and well-being. As founder of Jeff’s Gym, he's dedicated to creating a space where individuals discover strength, health, and lasting change. where he helps clients build strength, confidence, and lasting change through personalized training and small-group coaching focused on weight loss, muscle growth, and functional fitness.
Jeff’s fitness background is rooted in premium, high-expectation environments—supporting operations and member experience at Barry’s Bootcamp in New York and David Barton Gym in Chicago—later expanding into hands-on coaching and community-based wellness through the YMCA in Jacksonville.
Before settling on a profession in fitness and launching Jeff’s Gym, Jeff built a corporate career in sales, operations, and project management—most notably at Groupon—where he developed training processes, led operational improvements, and supported large-scale initiatives.
That blend of fitness experience and real-world business leadership shapes how Jeff trains: structured, measurable, and personal—so clients aren’t just getting workouts, they’re building a lifestyle they can maintain. Whether leading group sessions or working one-on-one, he instills purpose and determination that extends beyond the gym. His mission is clear: to empower individuals to look, feel, and be healthier for the long haul, by helping them prioritize their personal wellness.
