“I built the PostureRx Online Program to help you feel better, move better, and live better”

-Nathan Briner

Feeling Pain?

  • Is your aching back demanding your attention?
  • Are your shoulders starting to round?
  • Can you not stand up straight like you used to?
  • Does your body ache after work?
  • Have your knees and hips become stiff?
  • Do you suffer from painful movement or lack of flexibility?

Learn the techniques and exercises that have shown time and again to have a profound and lasting effect on these very issues. PostureRx is created from over 20 years of clinical and teaching experience, that will help you consistently produce positive changes in how you stand, feel and move.

Why PostureRx?

Poor posture, aches from work or injuries, stiff or painful movements are challenges everybody faces in their lives. They can steal our attention and prevent us from fully enjoying the activities we love to do. Not knowing how to fix them or how to answer the question “what should I do?” is frustrating and disempowering. PostureRx is a home program that uses the exercises, movements, and pain neutralization techniques that I offer in my sports therapy clinic and workshops that help people solve these issues. We address back pain, rounding shoulders, lost flexibility, balance and much more through a series of online videos that provide the tools, the education and the care you need to make the change. PostureRx guides you through safe and effective movements that leave you (regardless of age, experience or activity level) feeling balanced, mobile, and rejuvenated!

  • Life can be pretty busy and stressful, and I don't have the time to deal with chronic pain! So I was very excited to find pain relief, as well as greater strength and flexibility, through the simple movements of the PostureRx online program. In just minutes a day, I am feeling so much better - without drugs or surgery!

  • Before working with Nate I’d been experiencing a year of significant chronic mid back and neck pain. I’d given up exercising and was starting to come to terms with the hard truth that weight lifting was something my body was no longer able to do. A few sessions with Nate doing some hands on therapy and going through new movement patters catalyzed what is now a 90% improvement in pain and mobility, just 1 month later. I’ve overcome the fear that I’m going to hurt myself and have regained confidence in complex movements. I’m back to lifting weights, swinging kettle bells and doing what I enjoy most- movement.

Meet Nathan

I have been in the health and wellness industry for close to 20 years. I have spent thousands of dollars on education to learn how to help people feel better in their bodies, to help them understand pain, and to understand themselves. Throughout many of those years I felt that education had failed me.
