Charles Knowles
President & Professional Coach, Lululemon Ambassador
At Vision + Fitness and LOVE, we don’t just train bodies—we build stronger minds, communities, and lifestyles that transcend the gym. Leading this movement is Charles Knowles, a powerhouse coach, entrepreneur, and visionary who has dedicated his life to helping people unlock their full potential through fitness, mindset, and personal growth.
Charles’s journey began with loss. At just seven years old, he found his father after he had passed away from a heart attack at 39. His father had a big vision for life, but poor health cut it short. That moment shaped Charles’s mission to create a space where health, strength, and personal vision are never left unrealized. Vision + Fitness was built on that promise—that through movement, resilience, and community, people can take control of their lives and build something lasting.
As the Founder and President of Vision + Fitness and LOVE, Charles has spent over a decade transforming lives through his dynamic, holistic approach. His coaching goes beyond reps and sets—it’s about resilience, discipline, and creating a life that aligns with your highest potential. Through elite personal training, group fitness, and leadership coaching, he has built a reputation for developing athletes, business leaders, and everyday warriors into the strongest versions of themselves.
A Lululemon Ambassador and sought-after performance coach, Charles has trained CEOs, collegiate and professional athletes, and industry leaders. Over the years, he has worked with Philadelphia 76ers General Manager Elton Brand and his wife Seneca, Super Bowl-winning Philadelphia Eagle Jahan Dotson, former NFL player and reality star Devin Duggan, Michael Harris (CEO of Best Sports Consultants and former agent of Kobe Bryant), Frank Knuckles of The Roots, and Levi Brown.
Beyond high-level coaching, Charles is deeply committed to mentorship and giving back. He has spoken at schools about overcoming adversity and turning challenges into fuel for success, including speaking at his former middle school, inspiring the next generation to chase their dreams. He has also worked closely with D1 athletes and rising social media star Jake West, mentoring and motivating them through workouts that challenge both the body and the mind.
Through Vision + Fitness and LOVE, Charles has cultivated a community where fitness is more than just a workout—it’s a mindset, a family, and a path to long-term transformation. His coaching blends strength, resilience, and heart, creating a space where people not only train hard but also live with purpose.
Whether you’re stepping onto the training floor at Vision, sweating it out in a LOVE class, or seeking the guidance to level up in life, Charles is here to push you, believe in you, and challenge you to step fully into your power.
Your vision is possible. Let’s make it into a reality.
