One System, Backed by Real Experience

Coach Deris “DDunc” Duncan brings a former D1 athlete’s discipline and years of coaching experience to every session. A NASM Certified Personal Trainer with a Master’s in Exercise Science, Deris spent over six years as a regional head coach overseeing over a dozen head coaches and fitness managers across four Austin studios before founding DDunc Athletics out of his garage in 2025. In 2026, that grew into DDunc Athletics’ first studio location in Tarrytown. Every client trains within the same proven coaching system, tracked rep by rep, session by session. The attention is personal. The results are earned.

A Small Team, A High-Touch Experience

Every DDunc Athletics coach shares the same commitment to thoughtful programming, clear encouragement, and creating an environment built around personal attention.
