How We Work

Coaching built around
the barbell.

Strength that carries into every part of your life. We train systematically, progressively, and with purpose. No gimmicks. No shortcuts. Just the work.

Client deadlifting at Ground Zero Strength
The GZS Method

Strength is the base.

Whether you're 25 or 75, a competitive lifter or someone who's never touched a barbell — the system works the same way. Progressive, systematic, honest work.


Sam coaches lifters from 68-year-old grandmothers to amateur powerlifters, specializing in meeting you exactly where you are and moving you forward.

Ground Zero Strength is excellent for all ages to build strength and improve quality of life. Sam helped walk me through proper safe form on the major barbell lifts. I now have zero back pain, better posture, and less fatigue from daily tasks like stairs.

My husband and I have worked with Sam for close to 2 years. We started in group training and after moving across the country we continued with online coaching. Sam is very patient and taught us proper form while we got stronger than either of us thought possible.

Sam is an amazing trainer who really knows what he's doing and knows how to teach it in a way that makes everyone feel confident. I 100% recommend his barbell clinic and joining his gym. 10/10 experience.

Sam at Ground Zero Strength has been coaching me since July 2022. From day 1 I felt completely comfortable in his gym. I am 44 years old and I wish I had met Sam sooner in my lifting life!

I spent a great afternoon learning from Sam at Ground Zero's 1-1 beginner barbell clinic. Professional, informative, personalized and just good fun. The facility is awesome — a really cool space to get in the zone to lift.
