Nexus Health Tools creates compact manual tools with carefully considered contact shapes, starting with the psoas and iliacus.
Bryan Lee knows what it feels like to lose your life to pain. Not just the physical part — the weekends with his wife that turned into him lying on his back, unable to move. The marriage strain. The daily life that shrank down to what he could manage from a mattress.
Bryan sought professional care while exploring tools for his own routine. His choices reflect his personal circumstances, not advice for someone else to change or decline care.
He researched psoas and iliacus tools and compared their contact shapes. He wanted a compact design that brought two distinct tips into one tool.
But as an inventor at heart with a background in mechanical engineering and 3D design, Bryan couldn't accept defeat.
He spent over a year and a half designing, prototyping, testing, and refining. The result was Core Nexus: a broad tip for the psoas and a narrower angled tip for the iliacus in one compact manual tool.
Using the Core Nexus consistently was the turning point. Bryan started enjoying weekends again — actually doing things instead of watching from the couch. He got back to living with fulfillment.
He decided to make the design available to others. His personal experience does not establish typical results, determine suitability, or replace professional care.
That's why Core Nexus exists. Not because Bryan wanted to start a business — because he needed this tool to exist, and once it did, keeping it to himself felt wrong.
— Bryan Lee, Founder & Inventor
Two distinct contact shapes for the psoas and iliacus, brought together in a single-piece tool.
A broad tip designed for the psoas and a narrower angled tip designed for the iliacus. The tips are part of one solid piece; placement and angle are adjusted manually.
Different contact shapes offer different ways to apply manual pressure. Read the instructions and seek guidance about suitability.
Quick-start guidance and video tutorials explain product positioning. They are not a substitute for professional assessment or care.
Durable construction backed by a lifetime warranty. Precision-crafted in the USA with materials designed to perform for years.
From chiropractors to MDs to massage therapists — movement professionals trust Core Nexus for their clients and themselves.
