STRENGTH

TRAINING.

Strength training is the foundation for a stronger, healthier life. Our programs center on the big barbell lifts—squat, deadlift, bench press, and overhead press—paired with smart accessory work to build balanced strength, prevent injury, and boost performance. Strength training increases metabolism, burns fat, strengthens bones, and improves posture, confidence, and how you move through life. Whether you're aiming for peak performance or everyday vitality, strength training delivers results that last. Ask your doctor.

CONDITIONING.

A smart, sustainable conditioning program is essential for long-term health and performance. Our coaches design perfectly balanced cardiovascular training plans rooted in the science of polarization, periodization, and progressive overload. Whether you want to cycle faster, run longer, or simply boost your everyday fitness, we’ll help you build the engine to go the distance.

PERFORMANCE

TESTING.

To arrive at desired outcomes you must calculate the inputs. Knowing exactly what and how much takes the guesswork out. It’s arithmetic, not algebra. Tests include Resting Metabolic Rate (RMR), Peak Oxygen Consumption, Maximal Oxygen Consumption (VO2 Max), Lactate Threshold, Functional Threshold Power (FTP), Body Composition including DEXA Scan, running gait analysis, and bicycle fitting. We do not use outside vendors and all testing is conducted on-site at STRONG SPORTS GYM.

WiLL&KENGO

Founded in 2006, STRONG SPORTS GYM has evolved through multiple phases—from elite fight camp to a public training facility, and now, into its most refined form: a private, high-performance space dedicated to individualized coaching and small-group classes. 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 in Japan. Soon to be reunited at the Pasadena location, they aspire 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 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.
