Strength. Science. Success.

The Pasadena Standard for High-Performance Training

Located in the heart of Old Town at 985 E Colorado Blvd, Strong Sports Gym (SSG) is a private, meticulously curated strength and conditioning facility. We don't do "fitness fads" or generic workouts. Led by expert coaches WILL & KENGO, we combine decades of elite athletic experience with clinical-grade data to deliver a "No Fluff" approach to your health.

Whether you are an elite athlete or a professional looking to reclaim your vitality, our mission is simple: Stress. Recover. Adapt.

CONDITIONING.

We take the guesswork out of cardio. Using science-backed methods like VO2 Max testing, we build sustainable aerobic engines tailored to your specific physiology for sport or daily health.

PROGRAMMING

Generic workouts yield generic results. At SSG, we combine expert coaching with personalized nutrition and lifestyle strategies to optimize your performance. Our "Stress, Recover, Adapt" formula is the roadmap to your success. We provide the map; you provide the work. Together, we ensure every session moves the needle toward your goals.

PERFORMANCE

TESTING.

To reach your goals, you must measure your baseline. Strong Sports Gym is the only facility in Pasadena offering a full suite of on-site diagnostic testing. Our services include VO2 Max testing, Resting Metabolic Rate (RMR), Lactate Threshold, and Body Composition via DEXA Scan. No outside vendors—just professional-grade data to fuel your custom program.

WiLL&KENGO teams you up with a physical trainer and a programming coach to help you hit your goals faster—and safer.

With a down-to-earth approach built on years of real-world experience, our “2-on-1” coaching style mixes hands-on training, smart planning, practical nutrition tips, and progress tracking that actually makes sense.

Expert Coaching Since 2006

WiLL&KENGO

Founded in 2006, STRONG SPORTS GYM has evolved through multiple phases—from elite fight camps to a public training facility, and now, into its most refined form: a private, high-performance space dedicated to individualized coaching. WiLL&KENGO have been working together for over two decades—first as athletes and coaches, then as founders of STRONG SPORTS GYM in Los Angeles and STRONG SPORTS JAPAN in Komatsu, near Kanazawa. Now reunited at their Pasadena location, they're here to be more than just your trainers—they’re ready to be your coaches for life. BOOK TODAY.

Strong Sports Gym is located in the heart of Old Town Pasadena. Under its vaulted roof, you'll find a meticulously organized space filled with high-quality, no-nonsense equipment—everything you need, exactly when you need it. The environment is welcoming, the energy is focused, and the cleanliness is unmatched. It’s more than a gym—it’s a place built for serious training and real results.
