Square1 The SQUARE 1 System™ looks at the body totally differently than the conventionalists do.

Conventionalists tend to get caught up in symptoms but the SQUARE 1 System™ gets to the source of why you have pain, tightness, and weakness. SQUARE 1 (formerly called RESET) was developed by Shawn Sherman who holds a degree in Exercise and Sport Science from Penn State University. He has consulted with hundreds of elite athletes from many organizations including: Olympians - US, Canada and Russia; Professionals - Chicago Cubs, White Sox, Blackhawks, Bears, Bulls and Red Stars; Collegians - the Minnesota University Football, Northern Illinois University Football, Valparaiso University Basketball, Oakland University Basketball and the Missouri State University Basketball programs.

Most movement pros tend to chase noise… pain, stiffness, bad movement. But noise is just the symptom and rarely the source.

The real drivers? Tiny positions your brain quietly labels as “threat”: a forward head, a locked rib, an eye that doesn’t track smoothly. These threatened positions happen first, long before anything looks or feels “wrong.” Your neurology compensates, layer by layer, until one day the compensation becomes the obvious problem.

Most people wait for the pain. That’s fine, SQUARE 1 will still reverse-engineer every single layer of subconscious threat and clean it up with ridiculous consistency.

But you don’t have to wait.

If you’re alive, you’ve collected stress, trauma, and micro-injuries whether you feel them or not. There is always more horsepower hiding behind quiet threats.

SQUARE 1 doesn’t chase symptoms.

It interviews and nervous system and then deletes the reasons you needed symptoms in the first place.

Noise or no noise, there’s a better version of you waiting on the other side of a SQUARE 1 neuro- reset.

Low-key one of the coolest conversations I’ve had in a while.

Just me and breaking down how organizing someone’s nervous system changes… everything. Strength, pain levels, recovery, sleep, even mood.

At its core, SQUARE 1 is about upgrading neurological resilience to the exact life people already lead, so their system can stay calm and run clean no matter what life throws at it. When that happens, the results speak for themselves.

Appreciate you big time, Mark 🙌
