Pso-Rite vs. Core Nexus: Tip Shape and Muscle Reach
Core Nexus
Two muscle-specific tips: a broad tip for the psoas, a narrow angled tip for the iliacus.
📖 In This Article
Of these two tools, only Core Nexus has a different tip shape for each design target.
This article compares the Pso-Rite with Core Nexus. It focuses on tip shape, contact area, the base, material, and warranty.
The Pso-Rite's broad tips reach the psoas. They are too wide to hook into the iliacus.
Two Muscles, Two Locations, Two Shapes
The psoas and iliacus are hip flexors. They start in different places. This article looks at two tip shapes.
| Psoas | Iliacus | |
|---|---|---|
| Location | Deep in the abdomen, along the lumbar spine | Inside the bowl of the hip bone |
| Design target used here | Wider contact area for a psoas-oriented tip | Narrow, angled contact for an iliacus-oriented tip |
| Where it sits | Deep in the belly, along the lower spine | Inside the bowl of the hip bone |
NHT uses a wide psoas tip and a thin iliacus tip. This is a design review. It is not a guide to press the belly or inner hip rim.
The psoas begins along the lower spine. The iliacus begins inside the hip bone. Core Nexus uses a different tip shape for each design target.
Pso-Rite: Matching Broad Tips
The Pso-Rite has two matching broad, round tips. That shape reaches the psoas.
The design limit is the lack of a narrow, angled tip.
The iliacus starts inside the iliac fossa. The broad Pso-Rite tips are too wide to hook into that area.
This is not a quality claim. It is a scoped comparison of tip shape and contact area.
The Pso-Rite's tips are fixed. Changing the contact angle requires repositioning the body or tool. Core Nexus tips can rotate on the base. This is a usability difference, not proof of a better health result.
Bottom line: The Pso-Rite reaches the psoas. Its matching broad tips cannot reach the iliacus.
Compare Matching and Different Tip Shapes
Core Nexus: Different Tips for Different Muscles
Core Nexus was built on a simple idea: two different muscles need two different tips.
- Wider tip — NHT's psoas-oriented design, with a broader contact area.
- Curved tip — built for the iliacus. Narrower and angled to follow the curve of the hip bone inward, into the bowl where the iliacus lives. This is the shape the Pso-Rite does not have, because matching tips cannot do both jobs.
Core Nexus in use — the tips can turn as body position shifts.
Both tips can rotate on the base as body position changes. The Pso-Rite tips are fixed. This describes product movement, not a physical-therapy equivalent or a promised result.
The rotating tips can change angle as the body moves.

Why Both Muscles Are Compared
The psoas attaches along the spine. The iliacus attaches to the pelvis. They meet at the same spot on the thigh bone and work as one unit, the iliopsoas.
The pair joins near the thigh bone. Each starts in a different place. NHT uses a different tip shape for each area:
- The psoas starts along the lower spine. NHT uses a wide psoas tip.
- The iliacus starts inside the hip bone. NHT uses a thin, angled iliacus tip.
What that does for a given person varies, and no tool should promise a result. Front-of-hip tightness has more than one possible cause, and anything painful or persistent belongs with a qualified clinician.
The Two-Tool Problem
Here is the practical math of single-muscle tools:
If you want both contact geometries, the Pso-Rite provides only the matching broad shape. A separate narrow-tip product would be a second purchase.
That means two purchases and two products to store and learn. Core Nexus places both shapes on one base.
Core Nexus carries both shapes on one tool: a broad tip for the psoas, a narrow angled tip for the iliacus.

See the Pso-Rite and Core Nexus in the REACH Test
The REACH Test uses a true-to-scale hip model. Pick a muscle, place a tool, and see whether its tip gets to the target.
- Pso-Rite: reaches the psoas but cannot reach the iliacus.
- Core Nexus: reaches the psoas and iliacus with two different tips.

Who May Prefer Each Design
Pso-Rite May Be Right If:
- You want matching broad contact tips
- You already own a separate narrow-tip tool
- You prefer the Pso-Rite's fixed design and instructions
Core Nexus Is Built For:
- People who want two distinct contact shapes on one base
- People who want rotating rather than fixed tip angles
- People who want to compare the warranty, material, and build
- People who prefer one product rather than two separate tools
The Bottom Line
The Pso-Rite reaches the psoas but cannot reach the iliacus. Core Nexus reaches both muscles with two different tip shapes that rotate on the base.
The buying question is whether you want one broad contact geometry or two distinct geometries.
A symptom cannot tell you which muscle needs attention, and no product can promise a result.
Want two different tip shapes on one base?
Core Nexus comes with 30-day returns and a lifetime warranty against manufacturing flaws.
Frequently Asked Questions
No. The Pso-Rite reaches the psoas, but its broad, rounded horns are too wide to hook into the iliacus. The REACH Test shows this on a true-to-scale hip model.
The two muscles begin in different locations. NHT uses a broader contact area for its psoas-oriented tip and a narrow, curved shape for its iliacus-oriented tip. Do not treat this design explanation as instructions for deep belly or inner-rim pressure.
That depends on the contact shape you want. The Pso-Rite's broad tips reach the psoas. If you also want a narrow, angled tip for the iliacus area, Core Nexus carries both shapes on one base. Whether you need that is your call — this article compares design, not results.
The Core Nexus tips can turn on the base as body position changes. The Pso-Rite tips are fixed. This is a product feature. It is not the same as physical therapy.
Core Nexus has a second tip for the iliacus area. Each tip can turn on the base. The tool is made from TPU. Both products have lifetime warranties. The main difference is the set of tips.
That varies from person to person, and no tool should promise a result. Tip shape limits what a tool can reach; it does not decide how your body responds. Keep sessions gentle, let comfort guide you, and see a clinician for anything painful or persistent.
