Lead with purpose, move with confidence, and stay consistent, committed, and persistent for life.

No matter their past, we are excited to help them build their future.

Our motto for training is to build resilience, move with intention and purpose, and to build an engine that can power for a lifetime," proclaims Owner and Trainer, Oscar Charles, Jr.
Unlike traditional fitness approaches, Tri90 prioritizes the way your body is designed to move, rather than forcing it into rigid training methods.
Correct imbalances, prevent injuries, and train for longevity.
Develop strength at the joint level and in real-world movement patterns.
No more guessing. No more temporary fixes. This is lifelong fitness with a community that supports your journey.
Most fitness programs focus on aesthetics or short-term strength gains but fail to address the way your body is meant to move. At Tri90 Fitness, we believe in functional movement—helping you regain control, prevent injuries, and build lasting strength at the joint level. This isn’t about lifting heavier or just looking fit—it’s about moving better, feeling stronger, and living longer.
Move the Way Your Body Was Meant To
Before adding heavy weights or explosive movements, we reset and rebuild your foundation using:
Controlled Articular Rotations (CARs)
Improving joint mobility, resilience, and longevity by training each joint through its full range of motion.
Core Activation & Balance Work
Ensuring you control movement from the inside out, reducing injury risk.
Mobility & Corrective Drills
Fixing imbalances and movement inefficiencies before adding strength.
Get Strong Where It Matters Most
Once mobility and control are in place, we build strength at the joint level using:
Progressive Resistance Training
Strengthening muscles, tendons, and ligaments to support safe, sustainable strength gains.
Functional Movement Patterns
Training real-world movements that improve athleticism and daily life.
Stability Under Load
Applying CARs-based mobility work to ensure joints stay strong and mobile under tension.
Unlock Your Full Athletic Potential
With mobility and strength established, we train for explosiveness, agility, and dynamic movement using:
Plyometrics & Speed Training
For athletes looking to gain explosive power and professionals looking to regain athleticism.
Dynamic Strength Work
Incorporating controlled rotational and multi-directional movements to mimic real-life demands.
Advanced Loaded CARs
Applying joint-specific strength work under load, reinforcing long-term joint health.
