D1 Sports Franchise, LLC (D1 Training)

D1 Training is a fitness franchise specializing in athletic-based training programs for individuals of all ages and skill levels. Founded in 2001 by former NFL player Will Bartholomew, its mission is "To Be the Place for the Athlete," aiming to train the athlete in everyone through expert coaching, high-level programming, and a community focused on growth. The company is headquartered in Franklin, Tennessee.

D1 Training offers a comprehensive range of services, including scholastic training for youth athletes (ages 7-18), adult fitness programs, personal training, small group training, and specialized programs for collegiate and professional athletes. These programs are built on a "5-Star Training System" that emphasizes dynamic warm-ups, performance training, strength development, core and conditioning, and cool-downs, all delivered by certified coaches. The franchise model focuses on structured, coach-led workouts rather than open gym usage, targeting individuals seeking performance development and a team-oriented environment.

As of late 2025 and early 2026, D1 Training has been experiencing rapid expansion, with over 170 locations open nationwide and more than 200 additional franchises in various stages of development, with a goal to reach 200 open locations in 2026. The company has been recognized multiple times on the Inc. 5000 list as one of America's fastest-growing private companies. Will Bartholomew serves as the Founder and CEO, with Dan Murphy as Chief Operating Officer. Recent member surveys indicate a strong industry shift towards strength training, aligning with D1's core athletic-based model. The company is also reportedly exploring a potential sale.
