Coaching Built for Adults in Twin Falls
Ground Zero Strength opened in Twin Falls in 2021 on a simple idea: most adults do not need more fitness content. They need a clear training system and a good coach.
Sam Krapf, Starting Strength Coach
Sam is a Starting Strength Coach with a B.S. in Biology and an M.S. in Sports Performance, and a former college baseball coach. He has spent years teaching people to lift well and get measurably stronger.
He built GZS because he kept meeting adults who had been told to "just work out" with no idea what that meant. What they needed was coaching: a plan, good technique, and someone tracking the work and adjusting it. That is what good personal training should be, a strength coach with a plan, run in a small group so more people can afford it.
The philosophy is straightforward. Training should be efficient, measurable, adaptable, and sustainable. Strength should serve the rest of your life, so you can keep doing the things you care about instead of slowly removing every physical demand from your days.
