Core Nexus is the only tool with two distinct tips engineered for two distinct muscles. The wider tip targets the psoas (deep in your abdomen), while the contoured tip reaches the iliacus (inside the bowl of your hip bone). Other tools use identical tips or only address one muscle — leaving half the problem untreated.

The iliacus and psoas work together as the "iliopsoas" — your primary hip flexor group. The iliacus attaches inside your hip bone and is almost impossible to stretch or foam roll. When it's tight, it pulls your pelvis forward, compresses your lower back, and limits hip mobility. Releasing it is often the missing piece.

You'll feel productive pressure — similar to a deep tissue massage. You control the intensity with your body weight. Most users describe the sensation as "hurts so good" and feel noticeably lighter immediately afterward.

Most people notice a difference after their very first session. For lasting change, we recommend daily use for 2–3 weeks. That’s when chronic tension patterns start to permanently shift.

Many people with disc issues and sciatica find psoas and iliacus release helpful — tight hip flexors contribute to spinal compression. However, we always recommend consulting your healthcare provider before starting any new recovery tool.

Foam rollers and lacrosse balls work on surface-level muscles — they literally roll over the hip flexors without reaching them. The psoas sits deep in the abdomen, and the iliacus lines the inside of your hip bone. No amount of rolling will access either one. Core Nexus is shaped specifically to reach these structures with targeted, sustained pressure.

Yes. The psoas and iliacus are two distinct muscles with different locations and angles of access. The wider tip targets the psoas deep in the abdomen. The contoured tip reaches the iliacus inside the bowl of your hip bone. Using only one tip is like stretching one leg and not the other — you’re leaving half the problem untreated.

Yes — and that’s intentional. Core Nexus is manufactured using industrial-grade additive manufacturing with medical-grade TPU (thermoplastic polyurethane) — the same material class used in medical devices, orthotic insoles, and surgical-grade equipment. We chose this method because the dual-tip geometry physically cannot be made with injection molding.

Because the Core Nexus cannot be made with injection molding. Injection molds require simple shapes that can release from a two-part mold. The dual-tip rotating design, precision contact angles, and compound curves would be impossible — or require six-figure tooling. We chose the manufacturing method that serves the design, not the other way around. It costs more per unit. We do it because it produces a better tool.

Medical-grade TPU is inherently impact-resistant and fatigue-stable. Unlike injection-molded tools that can crack at weld lines and stress points, additive manufacturing builds the part as a single continuous structure — no weld lines, no inherent fracture paths. Core Nexus is built to handle years of regular use, backed by our lifetime warranty.

Use Core Nexus for up to 30 days. If you don't feel a genuine difference, email us and we'll issue a full refund — no hoops, no restocking fees. We also include a lifetime warranty against defects.

Every Core Nexus order includes the dual-tip tool, a quick-start guide, and access to our video tutorial library. Plus free shipping, a 30-day money-back guarantee, and a lifetime warranty against defects.

Black Swan is our 3-in-1 neck and hand relief tool. It combines suboccipital release (dual cradles for the base of your skull), gentle cervical traction (gravity-assisted neck stretch), and precision hand/forearm release (swan-head tip for carpal tunnel, tech neck, and hand tension). Under 4 ounces, no assembly, lifetime warranty.

Most tension headaches originate from tight suboccipital muscles at the skull base. These muscles tighten from screen time and forward head posture. Black Swan's dual cradle design targets exactly these muscles with gravity-assisted pressure. Many users report relief within the first session.

Yes — they complement each other. Core Nexus targets the hip flexors for lower back and hip pain. Black Swan targets the suboccipital muscles for neck tension and headaches, plus hands and forearms. Together they address the two most common tension points for desk workers and athletes: hips and neck.
