About JBS Fitness

About the Founder

Meet Will

Growing up, sports taught me consistency and discipline makes all the difference.

That passion led me to earn a degree in Kinesiology with a concentration in Exercise Science from Cal State Monterey Bay. Early in my career, I worked as a Strength & Conditioning Coach for Skyline College’s soccer program, where I learned how thoughtful programming, proper movement, and progressive training help athletes perform at their best.

From there, I transitioned into the role of Fitness Director for gyms, where I coached clients from all walks of life—from beginners taking their first steps toward better health to experienced lifters chasing new performance goals.

My job is to provide guidance, accountability, and evidence-based coaching to help you get you to your goals.

I don’t just tell you what to do, I help you understand why you’re doing it. When you understand the purpose behind your training, you’re more confident, more consistent, and better equipped to make healthy decisions long after our sessions are over.

My Coaching Philosophy

Everyone is Different

No two people have the same goals, movement patterns, training history, or lifestyle. Your program should reflect that.

Trust the Science

I use movement assessments, DEXA body composition data, and proven training principles to make informed decisions—not fitness trends.

Long-term Health

Looking better is a great goal, but lasting results come from building strength, improving movement, and creating habits you can sustain for years.

What Science-Based Coaching Means

Science-based coaching isn’t about making fitness more complicated. Every recommendation has a purpose, every exercise has a reason, and every program evolves as you do.

I coach using proven training principles that help you build strength safely, make measurable progress, and create habits that last.

Build a Strong Foundation

Good movement comes before heavy weight. We focus on proper form, mobility, and movement patterns to help you train safely and confidently from day one.

Train With Purpose

Every exercise is selected with your goals in mind. Whether you're building strength, losing weight, improving athletic performance, or simply moving better, your program is designed to move you toward that outcome.

Measure Progress

We don't rely on how you feel alone. Movement assessments, DEXA body composition scans, performance milestones, and regular check-ins help us track what's working and identify when it's time to make adjustments.

Adapt as You Improve

Your body changes as you get stronger. Your program should too. We continually evaluate your progress and make thoughtful adjustments so you're always challenged without being overwhelmed.

Stay Consistent

The best program is the one you can stick with. My goal is to give you the tools, education, accountability, and support to build habits that fit your lifestyle—not disrupt it.

Prevent Injury, Not Just Treat It

Long-term fitness means staying healthy enough to keep training. By emphasizing proper technique, appropriate progression, recovery, and balanced programming, we reduce unnecessary injury risk while helping you continue making progress.
