Who We Are

Donnaye James Wint
Co-Founder
Donnaye James-Wint is the driving force behind XB3 Fitness, a community built on energy, passion, and resilience.
His fitness journey began through early involvement in basketball and football (or soccer, depending on who you ask!). But it was athletics that truly sparked his enthusiasm—running fast, leaping far, and embracing any challenge that pushes physical limits. Donnaye’s love for movement fuels his mission to connect with others who crave momentum, vitality, and self-improvement.
“No matter the cards you’ve been dealt, you can still win the game of LIFE.” Donnaye
This personal mantra reflects his belief that fitness is for everyone—regardless of background or experience. At XB3, Donnaye is committed to creating an inclusive, supportive space where individuals at every level can take control of their health and evolve into the best versions of themselves.
With XB3 Fitness, it’s not just a workout—it’s a lifestyle.
It’s time to lock in. XB3.
