About PowerSource Performance Fitness
PowerSource Performance Fitness is a coached performance facility in the Santa Clarita Valley built for athletes and adults who want measurable results—strength, conditioning, and better movement. We combine high-standard coaching, intentional programming, and performance assessment tools to help you train with clarity and track progress over time.
Our Story
PowerSource began long before our doors opened in Santa Clarita.
In 1974, Aram Neserian opened Power Source Gym in Burbank, California—an invitation-only place built for serious lifters. As a teenager in the early 1980s, Eric Campbell earned an invite and was mentored by competitive strongmen, bodybuilders, and professional wrestlers. By 1985, Aram expanded into a 12,000 sq ft warehouse and kept membership limited to people who wanted a place to train, not a place to be seen.
Years later, Eric and Aram reconnected. After Aram passed away, Eric and his partners chose to carry that standard forward—building a modern performance facility that honors the original culture: high standards, real coaching, and a respectful training environment. That legacy became PowerSource Barbell Club, and today it continues through PowerSource Performance Fitness.
What We Are
We’re not a big-box gym, and we’re not a choreographed class studio. PowerSource is a coached training environment for people who care about progress—whether that means sport performance, event preparation, or simply building a stronger, more capable body.
Who We Serve
- Athletes (high school, club/travel, college, and competitive adults)
- Adults training for performance (strength, conditioning, HYROX-style goals, durability)
- Adults interested in the health and wellness aspects of regular exercise.
- The tactical community
- Youth development, including homeschool strength & conditioning options
What We Do
Our training is designed to improve:
- Strength and lifting technique
- Explosive strength and athleticism
- Mobility and movement quality
- Conditioning and work capacity
- Goal planning and body composition support
What Makes PowerSource Different
Coaching, not choreography. You’ll get real-time feedback, scaling, and progressions—not just a workout you follow.
A performance environment. Our equipment and training methods reflect what you’d find in serious performance settings—adapted to your level and goals.
Objective assessment options. When you want more clarity, we offer performance assessment tools (VALD) and body composition tracking (InBody) to establish baselines and measure change over time.
Standards and culture. We’re here to train. Respect the space, respect the people, and do the work.
