Tense muscles are constantly strained
Chronic hip flexor pain traces back to two muscles. Release them.
Most people don’t know they have an iliacus. Over 90% are tight there. It sits on the inside of the pelvic bone, and releasing it takes angular pressure through rotation. Static tools can’t produce that angle. The Hip Hook™ was designed to.
And if you want your psoas to relax, it won't unless the iliacus is released too.
The Hip Hook
- Reaches both hip flexors, the psoas and the iliacus
- Holds prolonged pressure for 90 seconds, the way a physical therapist would by hand
- The free app helps you set the pressure that is right for you

What a tight psoas & iliacus needs to relax
The muscles behind most hip flexor pain
The iliacus sits on the inside of the pelvic bone. Reaching it means coming in at an angle and rotating, which a foam roller, a static tool, or a massage gun can’t do by shape. The Hip Hook’s tip reproduces what a physical therapist’s thumb does, and you control the pressure the whole way. When the iliacus stays tight, pain shows up in the front of the hip, at the crease, and often in the low back or SI joint.
25 years to get the angle right
The tip shape, the height, the angle, the way pressure builds. Every dimension came out of 25 years of clinical practice and thousands of patients. Christine built the Hip Hook to reproduce what her thumb was already doing. Trying to copy the shape isn’t the same.
Tension doesn't stretch out. It also makes strain more likely.
The psoas gets all the attention. The iliacus, right beside it, is often why hips stay tight. Stretching lengthens both, but lengthening isn't the same as releasing. A flexible muscle can still hold tension at rest. That resting tension pulls constantly on the muscle's attachment points, and that pull is one reason chronic tension is a common setup for strain.
Strain, or just tight?
Most self-diagnosed hip flexor strains are chronic tension, not an acute tear. A sudden, sharp pain from a specific movement (a sprint, a kick, a slip on ice) is a true strain. Deep aching that comes and goes for months is usually a tension pattern.
Chronic tension can make a real strain more likely. When the muscle holds tension at rest, it's constantly pulling on its attachment points. Tissue that's pre-loaded like that has less slack to give when you sprint, twist, or lift.
Either way, the starting point is the same. Releasing the deep hip flexors, the psoas and iliacus, is what stops the constant pull. Stretching a strained or chronically tight muscle without releasing the underlying tension usually doesn't hold.
Measured hip flexor pain relief
*External studies and self-reported outcomes show that the Hip Hook (Mark) reduces pain, eases tension, improves sleep, and provides long-lasting results. Results may vary.
When & Where Hip Flexor Pain Hits
Sitting for Hours | Running | Standing Up
Tight Hip Flexors Can Affect Your Entire Body
When the iliacus, psoas, and hip rotators like the piriformis are tight, it tips and twists the pelvis and creates a ripple effect of pain and alignment issues through the hips, spine, and lower body.
- Pulls your pelvis forward
- Strains the SI joint
- Compresses the hip joint
- Twists the lower back
- Rotates your leg inward
- Strains the inside and compresses the outside of the knee
- Moves the patella laterally
- Overpronates the foot
- Strains the big toe
Signs that you have a tight hip flexor
Iliacus and psoas tension affects how the muscles and joints around the hip work.
- Hip joint pinching and grinding
- Hamstring flexibilty limitations
- Opposing glute weakness
- Glute and piriformis tension
- Leg rotates outward when you are lying on your back
- Decreased stride length
- Tenderness to touch on the front of hip
- Clicking and popping in the hip with motion
- Positive supine to sit test
Could this be your pattern?
The muscle tension explained
Everything You've Tried Works Better After This.
Physical Therapy. Chiropractic. Massage. Stretching. Strengthening. They all have value, but none of them release the chronic muscle tension that may be driving your pain. When tension in deep, overlooked hip flexor muscles is resolved first, everything else finally works the way it should. That's the piece that's been missing.

Chronic hip flexor pain doesn't need more effort. It needs the right muscles worked in the right order.
The Right Muscles
The iliopsoas complex (psoas & iliacus, commonly known as the hip flexors) contribute to tension in the back of the hip (piriformis & glutes) and drive the biggest ripple effects on alignment and pain up and down the body.
The Right Tools
Sustained prolonged pressure signals the nervous system to release. The Hip Hook is engineered by a physical therapist to mimic the precision of her hands, bringing professional-grade care into your home.
In the Right Sequence
Release comes first. Then alignment returns and pain fades. Only after that can stretching, strengthening, and recovery truly work. The method is simple and repeatable.

The clinician behind every Aletha tool
Christine Annie (Koth), MPT
Licensed Physical Therapist, author of Tight Hip, Twisted Core, biomechanist, and inventor
Christine didn't set out to build a wellness brand. She set out to solve a problem she kept seeing in her clinic.
Over 25 years of physical therapy practice, one pattern repeated itself. Patients arrived after they'd tried everything; PT, chiropractors, massage, stretching, strengthening, injections. They were diligent. They were exhausted. And they still weren't getting better.
What most practitioners were missing was chronic tension in certain key muscles, like the iliacus, that no foam roller or massage gun could reach. Christine could release it with her fingers. It worked. But there was a limit to how many hands she had, how many hours in a day, and how consistently a patient could access that kind of hands-on care.
So she designed the Hip Hook to replace her fingers.
Every tool in the Aletha line followed the same logic: take a hands-on clinical technique most people will never get enough of, and build a device that lets them do it themselves, at home, as often as their body needs it.
That's the through-line of this company. Not a trend. A clinician who got tired of watching people suffer inside a system that kept missing the same thing and decided to build the tools the system wasn't going to build on its own.
