    Absolutely love the Core Nexus Tool! It releases so much tension in my psoas and iliacus - feels like a deep reset every time I use it. Super effective and easy to use, whether it’s morning, night, before or after training. It’s become a daily essential in my recovery routine. Highly recommend to any athlete or anyone dealing with tight hips or lower back discomfort. Taking it with me everywhere I go!\\\" Dr. Michelle Goñi, MD

    I cannot speak highly enough of such an amazing product. For anyone suffering from low back or hip pain, the Core Nexus will specifically hit all of those targeted areas. As a chiropractor and also one who suffers from these conditions, it is a valuable tool and provides significant relief. This device can also be used on multiple areas of the body which is an added bonus. The Core Nexus does not disappoint. You will love it just like I do.\\\" Dr. David Sosa, DC

    As a certified massage therapist, I find the Core Nexus to be an exceptional tool for releasing tension in the iliopsoas. This muscle group is often challenging and time-consuming to manipulate, but the Core Nexus can be easily positioned and rotated to provide effective self release.\\\" Diane Carlisle, CMT

      Are You Suffering From Any of These?

      Desk Job Back Pain

      Eight hours of sitting, hunching, and stiffening. Your lower back screams every time you stand up. The pain is constant and getting worse.

      Sleepless Nights

      Pain that jolts you awake at 3 AM. Tossing and turning, trying to find a comfortable position. Exhaustion from never getting real rest.

      Sciatica & Nerve Pain

      Shooting pain down your leg that stops you in your tracks. Constant tingling and numbness that never goes away.

      Limited Mobility & Performance

      Your range of motion gets worse every month. Activities you used to do easily now cause pain. Your performance is declining, and you don't know why.

      Nothing Else Has Worked

      You may have explored various options—stretching, massage, and other therapies. While these can help, deep tension often returns. Standard methods can struggle to reach the deep psoas and iliacus, leaving the source of your discomfort untouched.

      Commuter Hip Tightness

      Every mile tightens your hips a little more. By the time you get home, you can barely walk without stiffness and discomfort.

      Target the Deep Lower Back & Hip Tension That Persists

      Introducing Core Nexus: The Unique Tool Designed to Release Both Your Psoas & Iliacus

      Wake up feeling more refreshed. Walk with looser hips. Stand up from your chair with greater ease.

      The Connection: Deep lower back discomfort often stems from hip tension. The psoas and iliacus—deep in your hips—can become tight. When they stay tight, they pull on your pelvis and spine, often contributing to deep discomfort.

      Many methods address surface symptoms, but may miss deep muscle tension. If the psoas and iliacus aren't released together, that deep tension often remains.

      Core Nexus is unique. It is designed to help release BOTH muscles with:

      • One tip shaped for your psoas, one for your iliacus tucked inside your hip bone • Rotates to work deeper as you release each muscle • 3-5 minute sessions

      Finally, a tool that targets the source of your deep tension. Release the muscles affecting your movement—so you can move freely again.

      Experience Complete Pain Relief And Peak Performance In 3 Easy Steps

      Step 1 - Position with Precision

      Position Core Nexus under your target muscle —use the psoas tip for your psoas, the iliacus tip for your iliacus.

      Step 2 - Release with Rotation

      Hold each position for 60-90 seconds, breathing deeply. Smoothly rotate on each tip to progressively work deeper into the tissue with each breath.

      Step 3 - Realign and Recover

      Use Core Nexus daily or as needed. Most users experience noticeable relief after their first session, with results improving over time as deep muscle tension releases, pressure eases, and your body moves with greater freedom.

      Why You'll Love the Core Nexus

      Why Other Tools Leave You Frustrated And Incomplete

      Tools with identical tips often face limitations. While the broader psoas receives pressure, the narrow iliacus tucked inside the hip bone can be difficult to access. A single tip size is rarely optimal for both.

      Small curved tip tools can reach the iliacus—but that same narrow tip may not effectively release the broad, deep psoas muscle. Often, a second tool is required for comprehensive relief.

      Multi-piece sets require swapping attachments between muscles. This interrupts your flow and can make the process feel like a tedious chore.

      Core Nexus fixes all of this. Each tip is shaped to reach the muscle it targets. Rotation that lets you apply pressure at any angle. No fighting, no swapping, no frustration.

      Target both muscles effectively in one 3-5 minute session—simplifying your routine with a tool purpose-built for deep relief.

      Stop Spending Hundreds $ Every Week Just to Feel Normal for Two Days

      You leave your manual therapy session feeling great—loose, mobile, and relaxed.

      But often, the tension returns. Frequent appointments can become costly and time-consuming.

      Manual therapy is effective because it reaches deep muscles and uses rotation to release them from different angles. However, visiting a professional every time tension builds up isn't always feasible.

      Our rotating tips are designed to simulate deep pressure, allowing you to target deep muscle tension in your own home whenever it appears.

      Access effective relief anytime you need it, on your own schedule.

      Never Deal With That Sharp Scary Pain When You Rotate Again

      You twist to grab something from your back seat and feel that familiar deep tightness or discomfort.

      When your psoas and iliacus stay tight, they can pull your pelvis out of optimal alignment and contribute to deep tension that radiates into the hips and legs.

      Standard stretches often struggle to reach deep enough to release them effectively.

      Our patent-pending rotating dual-tip design is engineered to target both the psoas and iliacus—addressing the hip flexor complex that often contributes to imbalance..

      Move through your full range of motion smoothly and confidently, helping to minimize deep muscle restriction.

      Get Your Rotational Power Back Without Expensive Training Programs

      Your golf swing used to feel smooth and powerful.

      Now you feel stiff when you rotate. You're losing distance, and your buddies are outdriving you by 20 yards.

      Tight hip flexors can limit rotational power in many sports - golf, baseball, tennis, basketball, football, martial arts, and more.

      When your psoas and iliacus can't lengthen properly, your kinetic chain efficiency often drops. You may lose the explosive hip drive that generates real power.

      Our targeted release is designed to help improve hip flexor mobility so your hips can rotate more freely and generate force through your movement.

      Work on reclaiming your distance independently, without always relying on expensive coaching or specialized treatments.

      I have gone through all the other psoas or iliacus tools on the market and this is far and away the best of all of them! The two different tips are excellent at getting to the psoas and iliacus. It’s high quality and I know this tool will never break unlike others I have had. Also what I like the most is now I have one great tool to do it all, and it is really convenient that I can do my Glute Medius, Quadratus Lumborum, and Tensor Fasciae Latae too, as these have been trouble areas for me as well. Considering I paid $200 for a tool that only releases the iliacus, this tool is a bargain because not only does it release the iliacus way better, it releases all the muscles I need to work on. I can’t recommend this tool enough!

      As a college lacrosse player, recovery is everything and the Nexus Health Tool has seriously become a game-changer in my routine. I’m constantly dealing with tight hips, sore quads, and the usual post-practice aches, but this tool helps me target those deep muscles I usually can’t get to with a foam roller alone. What I love most is how easy it is to use on my own especially for areas like the psoas and iliacus that are hard to release without a trainer. After using it consistently, I’ve noticed a big difference in how my body feels during speed work, lifts, and even just walking around campus. It’s compact, durable, and fits right into my sideline bag so I can use it between classes or right after a workout. Honestly, it’s one of those tools I didn’t know I needed until I tried it. Highly recommend it to any athlete looking to stay loose, recover faster, and perform at their best!

      Most of my day is spent working at a computer, I’ve struggled with lower back pain for years. I decided to give the Core Nexus a try, and I’m so glad I did! After just a week of using it for a few minutes each night while watching TV, I felt fast relief from my lower back pain. It’s easy to use and fits right into my evening routine. If you’re like me and spend hours sitting at a desk, I highly recommend the Core Nexus. It’s made a world of difference for my hip flexors and lower back!

        Why Core Nexus Is Superior To Alternatives

        ❌ Tools with Identical Tips

        Tools with identical dual tips look like they target both muscles, but both tips are the same size and angle. The broader psoas gets pressure, but the iliacus—a narrow muscle tucked inside your hip bone—requires a smaller, differently-angled tip. And without rotation? You're stuck with static pressure that limits depth and effectiveness. With identical tips only one muscle gets released. Your iliacus stays tight. Your relief stays incomplete.

        ❌ Small Curved Tip Tools

        Small curved tip tools feature a narrow, curved tip that can reach the iliacus tucked behind your hip bone—but that same small tip can't effectively release the broad, deep psoas muscle. The psoas requires a wider, taller tip to penetrate deep enough and distribute pressure across its surface. One tip can't do both jobs, leaving you needing a second tool for complete relief.

        ❌ Bulky Multi-Piece Systems

        Multi-piece systems require swapping attachments between muscles—interrupting your flow and turning relief into a chore. Worse, they use static pressure without rotation, limiting how deep and effective each release can be. Assembly hassles & incomplete release? That's a poor combination.

        When To Use The Core Nexus

        After Long Sitting Days

        Counteract hours of sitting with a quick 5-minute release—prevent the lower back pain and stiffness that comes from desk work.

        Pre-Workout Prep Sessions

        Unlock full hip mobility for explosive power and unrestricted rotation—without the stiffness that limits your performance.

        Post-Run Recovery Time

        Target tight hip flexors post-run to help minimize tomorrow's stiffness and deep tension before it sets in.

        Before Bed

        Release tension before bed to wake up pain-free—instead of shuffling out of bed with a seized-up back.

        Universal Athletic Performance

        Prime your body before competition for explosive movement and unrestricted range—perform at your peak rather than fight tightness.

        Long Flight Recoveries

        Restore mobility after long flights—counteract hours of cramped sitting that compress and tighten your hip flexors.

          What Happens If You Do Nothing?

          ⏰ Time Lost

          Countless hours spent on appointments, managing discomfort, and sitting out instead of living your life. Time with family and friends sacrificed to limitation.

          👤 Identity Diminished

          You may feel limited compared to the active, energetic person you once were. Stiffness and tension can define your day, feeling like the person who has to say no or can't keep up.

          💰 Recurring Costs

          Significant funds allocated to ongoing therapies, appointments, and temporary solutions. The financial commitment continues when the source of deep tension remains unaddressed.

          ⚡ Energy Depleted

          Persistent tension drains your energy. Movement feels harder. Rest feels incomplete. You wake up feeling less than refreshed, making it harder to give your best to your work, your family, or yourself.

          ⭐ Lifestyle Affected

          You might feel like the person who has to cancel plans or limit physical activities. Your mobility restrictions can affect your confidence and your ability to participate in daily life.

          Don't wait. Prolonged tension often leads to compensated movement patterns. Don't let another day pass without addressing the source of your discomfort.

          Frequently Asked Questions

          Not at all! Simply wash with warm soap and water after each use. The medical-grade TPU material is hypoallergenic and designed to stay hygienic with minimal effort. Unlike porous foam rollers that harbor bacteria, the Core Nexus maintains its effectiveness and cleanliness for years.

          The Core Nexus is specifically engineered to target both the psoas AND iliacus muscles—often the source of deep lower back and hip tension. Our patent-pending dual-tip design is built to reach these deep muscles that generic tools may struggle to access, aiming to provide relief where surface-level solutions haven't reached. You can also use the Core Nexus on different muscles, such as the QL, TFL, glutes, and more.

          The Core Nexus is crafted from Thermoplastic Polyurethane (TPU) and is exceptionally durable, with a bit of flex. It's hypoallergenic, non-toxic, and manufactured in the USA under strict quality standards. Unlike cheap ABS plastic tools, our TPU will stand the test of time and let you mimic a therapist's touch while remaining virtually unbreakable.

          Many users experience relief during their first session. However, since the psoas and iliacus muscles often hold significant tension, most people notice consistent improvement within 1-2 weeks of regular use. The key difference is that you are targeting the deep muscles directly, rather than just surface-level tension.

          Yes, the Core Nexus is designed for self-use. The smooth, contoured tips and rotating design help minimize the sharp sensation often found with static tools. We include comprehensive video instructions, and the tool's ergonomic design helps guide you to effective positioning. We recommend starting gently and letting the tool do the work.

          While generic tools may cost less upfront, they often lack the specialized design needed to reach the deep psoas and iliacus muscles where deep tension often accumulates. The Core Nexus is engineered to target these areas with precision, allowing you to manage deep muscle tightness effectively at home. Built to last a lifetime, it offers a durable, professional-quality solution that provides value for years to come.

          Yes! We stand behind the Core Nexus with our satisfaction guarantee. If you don't experience the deep release or mobility improvement you were hoping for within the return window, we'll refund your purchase. We're confident this tool can help provide the relief you've been searching for, but we want you to feel secure in your investment.

          Black Swan

          Great pain relief tool

          I work at a desk all day, which usually leaves me feeling pretty stiff, especially in my neck and forearms from all the typing. I picked this up hoping to work out some of that tension, and it has been excellent. The design is really clever because the different widths allow me to switch between targeting the deep pressure points in my neck and rolling out the tightness in my arms. It’s firm enough to really get into the muscle belly but simple to use while just relaxing on the couch. If you deal with muscle tightness or fatigue from computer work, this is a fantastic tool to have on hand.

          5.0 out of 5 stars The Black Swan is a Star!! 🤩⭐️

          I picked up the Black Swan for neck tension, and the two cradle widths are the star. They make it simple to dial in the right spot: the narrow cradle reaches the smaller areas high up near the base of the skull, and the wider cradle gives broader support lower near the base of the neck. After a few minutes, my neck feels looser and more comfortable. Easy to position anywhere it's needed and is excellent for quick resets during the day.

          Nifty Tool!

          I love the Black Swan. The head and beak make it easy to apply slow, steady pressure to tight spots in my hands, which feels great after playing a round of golf. It's simple to position around my neck and skull, and a few minutes helps ease everyday tension and stiffness. It's well-made, easy to control, compact, and easy to use. Helps me target knots, and I notice quick comfort and better mobility after short sessions. It's become a go-to tool for me.

          Awesome for neck tension

          I got the Black Swan to help with neck soreness and discomfort. Wow, this cool little tool does the trick. The freedom of placement with the varying widths is great, allowing me to get to where I need the pressure. I have another foam traction pillow, and it doesn't give me the freedom to target all the tender spots in my neck like the black swan. It is now always on my end table for whenever I need it! Makes a nifty little gift, too!

          It works as described.

          Friend of mine turned me on to this product…I approached it with great skepticism as I have suffered spinal problems for 25 years and more. Years of chiropractic, physical therapy and spinal injections provided little to no relief, and then this…the black swan. This strange looking product couldn’t possibly provide relief, or could it? Based on my friend’s absolute endorsement and his sworn testimony that this product works, he convinced me to take his home and try it for a couple of days, I reluctantly did. Thank you David! After only three days of using the “Black Swan” I can miraculously report considerable relief from ages of spinal pain that I have never experienced from other conventional cures and remedies. I ordered my own today.

Definitely recommend it to any pitcher looking for a reliable tool like this.

          I love the Core Nexus and the way it is so easy to find the psoas and iliacus muscles! It has really improved my hip mobility along with all of my leg muscles. I have always had bad hips and mobility which caused me to pull other leg muscles but with only one week of using the Core Nexus, I already feel looser and more agile! I would really recommend this product!

          It works! It goes Deep!

          If you have tight hip flexors this is your go to. Sturdy. Durable. I love it. It hurts at first if you’re sensitive. Stick with it for a few seconds and build up to longer time periods. It gets deep into the muscle tissue.

          Game-Changer for Athletes!

          As a college soccer athlete, I’m always looking for tools that help with recovery, mobility, and injury prevention. The Core Nexus has been a complete game-changer for me! After intense training sessions and games, my hip flexors and lower back can get super tight, but this tool provides deep, effective relief like nothing else I’ve tried. The stability of the Nexus is impressive—it stays in place while I use it, allowing for precise, controlled pressure on my psoas and iliacus muscles. It’s easy to use, durable, and truly helps with flexibility and recovery. Whether it’s for muscle maintenance or post-game recovery, I highly recommend it to any athlete looking to improve performance and prevent injuries. If you’re serious about mobility and recovery, this is a must-have!

          5.0 out of 5 stars Fantastic Mobility Tool

          The Core Nexus Health tool has been a great tool in enhancing my flexibility in many ways. I am a two sport college athlete playing both baseball and football and this tool has helped ensuring my optimal performance in both respective sports. I also use this tool before workouts as well and find it beneficial before performing workouts such as squats or deadlifts. I find it very stable when using it on my psoas and iliacus muscles, as having both of these muscles loose and free is crucial for my success on the field. I have had experience with SI joint issues in the past and this tool has helped alleviate that pain and I continue to use it for preventative care. If you need to relieve pain or enhance performance I would highly recomend the Core Nexus!

          Black Swan

          Great pain relief tool

          I work at a desk all day, which usually leaves me feeling pretty stiff, especially in my neck and forearms from all the typing. I picked this up hoping to work out some of that tension, and it has been excellent. The design is really clever because the different widths allow me to switch between targeting the deep pressure points in my neck and rolling out the tightness in my arms. It’s firm enough to really get into the muscle belly but simple to use while just relaxing on the couch. If you deal with muscle tightness or fatigue from computer work, this is a fantastic tool to have on hand.

          5.0 out of 5 stars The Black Swan is a Star!! 🤩⭐️

          I picked up the Black Swan for neck tension, and the two cradle widths are the star. They make it simple to dial in the right spot: the narrow cradle reaches the smaller areas high up near the base of the skull, and the wider cradle gives broader support lower near the base of the neck. After a few minutes, my neck feels looser and more comfortable. Easy to position anywhere it's needed and is excellent for quick resets during the day.

          Nifty Tool!

          I love the Black Swan. The head and beak make it easy to apply slow, steady pressure to tight spots in my hands, which feels great after playing a round of golf. It's simple to position around my neck and skull, and a few minutes helps ease everyday tension and stiffness. It's well-made, easy to control, compact, and easy to use. Helps me target knots, and I notice quick comfort and better mobility after short sessions. It's become a go-to tool for me.

          Awesome for neck tension

          I got the Black Swan to help with neck soreness and discomfort. Wow, this cool little tool does the trick. The freedom of placement with the varying widths is great, allowing me to get to where I need the pressure. I have another foam traction pillow, and it doesn't give me the freedom to target all the tender spots in my neck like the black swan. It is now always on my end table for whenever I need it! Makes a nifty little gift, too!

          It works as described.

          Friend of mine turned me on to this product…I approached it with great skepticism as I have suffered spinal problems for 25 years and more. Years of chiropractic, physical therapy and spinal injections provided little to no relief, and then this…the black swan. This strange looking product couldn’t possibly provide relief, or could it? Based on my friend’s absolute endorsement and his sworn testimony that this product works, he convinced me to take his home and try it for a couple of days, I reluctantly did. Thank you David! After only three days of using the “Black Swan” I can miraculously report considerable relief from ages of spinal pain that I have never experienced from other conventional cures and remedies. I ordered my own today.

          Better than the hip hook

          Works way better than the hip hook. In addition to this being more versatile, it gives much more relief. The hip hook is just too weak.

          Amazing Relief for Psoas & Iliacus Tightness

          Absolutely love the Core Nexus Tool! It releases so much tension in my psoas and iliacus - feels like a deep reset every time I use it. Super effective and easy to use, whether it’s morning, night, before or after training. It’s become a daily essential in my recovery routine. Highly recommend to any athlete or anyone dealing with tight hips or lower back discomfort. Taking it with me everywhere I go!
