About

Nathan Kershner, BS, CPT

I am a scientist by nature. I observe and learn. I want to know everything. I’m fascinated by how things work—our bodies, our minds, our world.

And I believe that changing your body can change your life. I believe that a healthy, versatile, functional body is the foundation for optimal health and performance in all domains of life.

In the last decade, I have helped people achieve goals in the role of challenge course facilitator, rock climbing instructor, martial arts instructor, and finally as a personal trainer. My favorite part of each of these roles has been helping people to conquer their fears and reach their targets.

In my full-time life during that same decade, I was first a college student studying biology, then a technician in two great research laboratories, and now a proud at-home dad to a wonderful son.

I am on a mission to empower people to improve their health and fitness for life, while steering clear of all the hype, misinformation, misapplied science and just plain bad science that pervades the fitness industry.
