Lion Heart Boxing Gym brings together the rigor of real fight training and the intensity of conditioning work in a setting shaped as much by discipline as by community. The gym’s identity is rooted in boxing as both a craft and a character-building practice: technical instruction, demanding physical effort, and hands-on coaching are treated as inseparable parts of the experience. Rather than reducing boxing to a generic fitness format, the approach keeps the sport itself at the center, using its structure and demands to build resilience, focus, and work ethic. That emphasis is reinforced by the coaching roster.
Classes are led by former and current professional boxers, seasoned ringside coaches, and long-time trainers, giving the studio a distinctly credible, gym-floor sensibility. Several sessions are taught by former IBF and IBO Light Heavyweight World Champion Glen Johnson, whose presence shapes both adult and youth training. His technical boxing and strength class pairs ring fundamentals with physical development, while the youth program channels boxing technique into lessons in resilience and character. Across the schedule, the training has range without losing its boxing foundation.
There are technical and strength-based sessions, advanced mitt and bag work, and high-intensity formats built around plyometrics, burnout rounds, and conditioning. Owner CJ “Lion Heart” Jackson leads a cardio-heavy plyometrics class, Jose Roman runs an advanced hour-long bag and mitt clinic, and Cam Adams teaches a demanding session that blends technical drills with sustained high-output rounds. Each format draws from a different side of the sport, from precision and mechanics to endurance and explosive athleticism.
What ties the gym together is a clear philosophy: boxing should challenge the body, sharpen the mind, and develop heart. The atmosphere is intentionally demanding, but not exclusionary. Lion Heart Boxing Gym is built around the idea that strong coaching and a hard-working group can push people beyond simple fitness goals toward greater discipline, confidence, and commitment.
