Our Credentials

Hear from Sam Pitcairn

Essential Strength: The Product of 10+ Years. 10,000+ Hours. One Relentless Mission.

The Problem

To the person looking for more than just a workout: My name is Samuel Pitcairn. I am the founder of Essential Strength, and I built this facility for one specific reason: I was tired of watching people settle for mediocrity in their healthcare and training.I have spent over a decade obsessed with solving the problems that most coaches - and even clinicians - won't touch.

My Solution

Everything we do is the culmination of everything I have learned, tested, and refined in world-class medical facilities and private labs.

My Promise to You

I earned my Master’s Degree in Sports Science from the University of Pittsburgh and my Bachelor’s Degree in Exercise Physiology from Ohio University. I am a USAW Certified Coach and have served as a Sports Scientist for Pitt and led return-to-play programs at UPMC. But I believe degrees are just paper if you can't apply them. That is why I traveled the world to study under legends like Charles Poliquin and Ben Prentiss. I immersed myself in the clinical philosophies of the Postural Restoration Institute (PRI) and the Gray Institute. I did this to ensure that when you walk through my doors - whether you are an elite Division I athlete or someone just trying to get out of chronic pain - you are getting a system that works.

If you are ready for a higher standard of coaching, welcome to Essential Strength.

"Every piece of content on our site - from blogs to programs - is a snapshot of what I’ve lived, tested, and refined.

Everything I write is the systems I’ve used to help clients break through plateaus, overcome pain, and transform their bodies and lives."
