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

With our 90-day program, we know we can help our clients reach their next level of fitness. We customize each plan to meet the individual needs of our clients. Let us work with you to find and maintain the changes you have been looking to make to your lifestyle.

No more guessing. No more temporary fixes. This is lifelong fitness with a community that supports your journey.

The Tri90 System Functional Fitness for Life

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.

STABILIZATION

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.

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.

POWER

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.

We Just Need Your Commitment to You.

There’s no greater investment than your health. In 90 days, we know you’ll not only see changes in your body, but you’ll also feel stronger, more confident, and inspired to care for your overall wellness, inside and outside the gym. If you’re ready to start making better choices and show up for yourself in ways you may not have in a long time, we're here to guide you every step of the way.
