During his tenure at 24 Hour Fitness, Sanft has guided the company in a number of carefully crafted initiatives—piloting the company's successful approach to its personalized membership pricing structure (responsible for driving increased club traffic coupled with demand for mind and body wellness), spearheading the return of 24/7 club operations for the majority of its club members nationwide, while developing new concepts including MODUS small group training, the HIIT+mindfulness program, P.A.S.E. Factor; and forming industry partnerships, such as those with nutrition, supplement and wellness provider Nutrishop, and recovery program creator iCRYO.

Sanft offers a wealth of experience and knowledge to 24 Hour Fitness from his nearly 30-year career building and managing consumer-focused companies where he has been responsible for growing revenue and developing strong talent. This experience, along with his extensive field leadership roles and the multiple organizational transformations he has led throughout his career, serves as an invaluable asset to the 24 Hour Fitness team as it continues to expand its U.S. presence.
