D1 Training Appoints Clif Marshall to Lead Pro Training Division Amid National Expansion
D1 Training's appointment of nationally recognized strength coach Clif Marshall signals a strategic expansion of its professional athlete training programs, positioning the franchise for accelerated growth in the competitive sports performance market.

D1 Training has appointed Clif Marshall as Senior Director of Coaching and Pro Training, bringing over 20 years of elite athletic training experience to the growing fitness franchise. Marshall's career includes coaching stints at Indiana University, University of Dayton, and the Cincinnati Bengals, where he developed a reputation for training high-profile athletes across multiple professional sports leagues.
Marshall's appointment carries significant implications for D1 Training's market positioning and service offerings. His track record includes helping athletes secure contracts totaling more than $1.89 billion while training MVPs, Defensive Players of the Year, All-Stars, and First-Round Draft Picks. This expertise directly enhances D1's credibility in the competitive sports training industry, particularly as the company expands its professional athlete services.
The strategic hire comes during a period of rapid expansion for D1 Training, which currently operates more than 155 facilities nationwide with 34 new openings in 2025 alone. Marshall will spearhead the development of D1's Pro Training Program from its Franklin, Tenn. headquarters, focusing specifically on preparing collegiate athletes for the NFL and NBA combines. His previous decade-long experience as Performance Director at Ignition Athletics, where he led its NFL Combine Training Program, provides a proven model for D1's expansion into professional athlete development.
Founder and CEO Will Bartholomew emphasized that Marshall's training philosophy extends beyond physical performance to building athletes from the inside out. This holistic approach aligns with D1 Training's existing five tenets of athletic-based training: dynamic warm-up, performance, strength, core and conditioning, and cool down. The integration of Marshall's methodology strengthens D1's position in the growing market for comprehensive athletic development programs.
The appointment reflects broader industry trends showing increased demand for specialized training facilities. D1's growth is fueled by expanding interest in scholastic training, particularly as competitive youth sports create greater need for skill development venues. Combined with the company's adult and personal training offerings, this creates a diversified market approach that addresses multiple demographic segments simultaneously.
Marshall's leadership comes at a critical juncture for D1 Training, which awarded 38 new territories year-to-date driven by record-breaking sales and innovative partnerships. His appointment signals the company's commitment to elevating its combine preparation programs and strengthening its franchise network through enhanced training methodologies and professional athlete services.
