About
Resistance Labs is the personal training and nutrition coaching practice I built around one idea: understanding beats willpower. Willpower runs out.
I gained 30 pounds of muscle during the 2020 lockdown. Went from 215 to 245, and it wasn't an accident. I spent years learning why things work. I earned a Kinesiology degree from Cal State San Marcos and stacked ISSA certifications in personal training and nutrition on top of it.
Most programs fail because they're built for a hypothetical person. Not you. Your schedule, your body, your history, none of it looks like the template someone downloaded off the internet. So I don't use templates.
What you get:
• Custom training built around your life. Not a PDF. A program that actually fits the gym you have access to and the time you actually have.
• Weekly check-ins. We review the data, adjust what isn't working, and keep what is.
• Form reviews by video. You film a set, I tell you exactly what to fix. This is how you stay safe and actually progress.
• Nutrition that isn't a diet. I'm not going to tell you to stop going to Chipotle. I'm going to tell you what to order. Weight loss is a math problem
with a psychology problem stuck to it, and I help with both.
• A reason for every rep. Most trainers hand you a program. I hand you a program and explain why every piece of it exists.
I'm 6'8", 255, and I train the way I coach. But this isn't about me. It's about you getting strong, lean, and actually feeling good in your own skin again.
The first session is a free assessment. No pitch, no pressure. Book it just to find out if you're the right fit for me.

Sam is the best! Ive always had a thin frame as a former basketball player, and no matter what I tried, I struggled to put on weight and build muscle. With Sams guidance, I went from 183 lbs to 195 lbs in about five months, and it was quality muscle. My strength went up in every lift, and I can feel the difference when I play basketball now that the new strength is coming through.Sam gave me clear workout plans, great lifting instruction, and nutrition advice that was simple to follow. I wish I had this kind of training and extra muscle back in college.If youre someone whos been stuck trying to gain size or strength, I cant recommend Sam and Resistance Labs enough.

Came to Sam wanting to lose 20 lbs and needed help with nutrition. He broke everything down in a way that made sense and I actually stuck with it. Hit my goal in 3 months. If you're looking for a trainer who knows nutrition too, this is your guy.

Resistance labs has completely transformed my training experience! Sams not only helped me improve my form but he also ensures that every minute in the gym is purposeful and effective. Beyond the physical aspect, Sam really helped me push past my mental limits and realize what Im really capable of in the gym. Since working with him Ive seen incredible results. I highly recommend him to anyone looking for a knowledgeable, reliable and, motivating trainer!
