This Is Not a
Traditional Gym.
Strata Strength Lab is a youth climbing, obstacle, movement, and strength development facility in Oroville, CA. We help kids and teens ages 1 to 18 build strength, confidence, coordination, and real-world capability through fun, coach-led challenges including Ninja Warrior-style obstacles, a climbing wall, and structured strength training.
Youth Strength & Movement. Done Right.
Most programs offer access to equipment or a class schedule. Strata offers a system. We are not a fitness center with a children's corner bolted on. We are a development environment built from the ground up around how young bodies actually learn to move, perform, and grow stronger through structured, progressive training.
Every session at Strata has a purpose. Every movement has a standard. Every athlete, whether they are 7 years old or 17, is held to the same principle: earn your strength through the work. No shortcuts. No gimmicks. No random workouts dressed up with motivational language.
The name Strata comes from geology, the study of layers. The earth's strongest formations are built under pressure, over time, one layer on top of another. That is exactly how we build athletes. Layer by layer. Rep by rep. Until the structure holds up under anything.
“Capability over appearance. Progression over random workouts. Structure over chaos.”
Strata Strength Lab
Three Pillars. One System.
Strata is built around three interconnected training disciplines. Together they develop the full athlete. Not just one quality in isolation.
Pillar One
Ninja Warrior Obstacle Training
Our obstacle course system develops the full athletic spectrum: coordination, grip, agility, body control, and mental grit. Athletes learn to move through challenge, not around it. Every obstacle is a lesson in what the body is capable of when trained with purpose.
Pillar Two
Climbing Wall & Grip Development
The climbing wall is not a novelty. It is one of the most effective strength and movement tools in the facility. Climbing builds grip strength, pulling power, core stability, spatial awareness, and problem-solving under pressure. It is foundational to everything we train.
Pillar Three
The Forge Protocol
Our structured strength training system built on discipline, repetition, and progressive overload. The Forge Protocol teaches real-world strength through the foundational movement patterns: squat, hinge, push, pull, carry. Applied with structure and intentional progression. Strength earned through the work, not shortcut.
Structured. Progressive. Skill-Based.
Training at Strata is not a rotating collection of random workouts. It is a structured system where each session builds on the last. Movement patterns are taught before load is added, load is added before intensity is pushed, and intensity is only pushed when the foundation is solid.
This applies to a 9-year-old learning to hang from a bar for the first time and to a 35-year-old developing their first real strength base. The standard is the same. The progression is earned, not assumed.
We measure progress in capability: what athletes can do, control, and sustain. Not in how they look or how much they can lift before they're ready.
Toddlers to Teens, Every Stage, Every Level.
Toddlers & Little Athletes
The earlier a child learns to move well, the longer that foundation serves them. We introduce the youngest athletes to structured movement, body awareness, and coordination in an environment built for their stage of development.
Kids (Ages 6 to 12)
This is the prime window for athletic development. Kids at Strata build real strength, movement skills, and confidence through structured obstacle training, climbing, and the Forge Protocol. Coached and progressive, never random.
Teens (Ages 13 to 18)
Teenagers who train with structure and purpose during these years carry that capability for life. Our teen programs develop serious strength, coordination, and discipline at the exact moment the body is most ready to absorb it.
What Athletes Walk Away With
Not a number on a scale. Not a before-and-after photo. Real capability. Built through real work.
Meet the Head Coach.
Head Coach & Co-Owner
Darrell Thompson
Darrell Thompson has been training and developing strength since 2006. Over two decades of hands-on experience in strength training, movement, and athletic performance. His background extends beyond the gym into a lifetime of athletic disciplines, including soccer, basketball, snowboarding, skateboarding, and combat sports.
As the co-founder of Cultivate Power Fighting Arts and the creator of The Forge Protocol, Darrell's approach to training is built on structure, discipline, and real-world capability. Not trends or gimmicks. His system focuses on developing strength that transfers: grip, coordination, balance, and power under pressure.
Through Strata Strength Lab, he brings that philosophy into a new environment. Blending obstacle training, climbing-based movement, and structured strength work to build resilient, capable young athletes, toddlers to teens.
Darrell is also a co-founder of Oroville Youth Forge, a local initiative providing training scholarships to young athletes in the community.
His mission is simple: develop strength that holds up in the real world.
Kids' Head Coach
Amory Thompson
Amory Thompson began strength training at just five years old, developing under the same principles that would later become The Forge Protocol. Raised in a disciplined training environment, she has spent her life building strength, coordination, and capability through consistent, structured practice.
A lifelong athlete with a strong foundation in combat sports, Amory has competed in judo and extensively in Brazilian Jiu-Jitsu. She is a black belt under Erik Paulson through Combat Submission Wrestling (CSW), reflecting years of dedication to technical mastery and performance under pressure.
As the head kids' coach at Cultivate Power Fighting Arts, she specializes in developing young athletes through structured training that builds real strength, confidence, and discipline. At Strata Strength Lab, she brings that same approach into strength and movement training, helping the next generation develop capability that carries beyond the gym.
Her focus is simple: build athletes who are strong, capable, and prepared.
