"Training with Darian is intense but always perfectly dialed to your level. He blends data-driven, science-based programming with full-stack support—from macro counting on a plant-based diet to pre-/post-workout routines—so every session feels personalized and purposeful.

"Training with Darian completely shifted how I think about pushing myself. His focus on quality over quantity challenged me to be intentional with every set—and to actually push to failure. His knowledge and coaching gave me a new perspective on training, and it's made a lasting impact on how I approach fitness."
