Contact our store ↗What is included in the price?
Hip Hook includes Orbit. Range is the upper-body tool. Full Body System includes both release tools, Orbit, Band and the paperback book. Orbit, Band and the paperback are also sold separately. Each product page lists its contents.
Which tool should I start with?
Hip Hook focuses on the deep hip flexors. Range focuses on the neck, upper traps and chest. Full Body System brings the tools together. Our product guide helps compare them; a healthcare practitioner can advise whether a tool is suitable for you.
Will it work for everyone?
Results vary. Muscle tension is only one possible contributor to discomfort. Aletha’s small study is encouraging, but it does not prove that these tools treat every cause of pain. Persistent or worsening symptoms should be assessed by a healthcare practitioner.
Do I need the app or a subscription?
No subscription is required to use the physical tools. Step-by-step instructions are available here in the store. Aletha’s optional free iPhone app provides tool guidance and a 90-second timer.

Neck Pain
Tightness in the suboccipitals (neck) and upper traps from forward head posture strains the joints and discs of the neck, while a tight pec minor rounds the shoulders and affects neck alignment.
Shoulder Pain
Tightness in the pec minor (chest) and upper traps pulls the shoulders into a rounded posture, narrowing the space for the rotator cuff and bicep tendon with every reach and lift.
Jaw Pain
Jaw pain is often the last link in a chain of tension that starts in the pelvis and works its way up through the spine, neck, and skull, which keeps the jaw clenched and overworked.
Headaches
Tension in the upper traps and suboccipitals (neck) can develop trigger points that refer pain directly into the head, leading to tension-type headaches.
Hip Pain
A tight iliacus pulls the pelvis forward and compresses the hip joint, creating pinching or irritation that can mimic arthritis, labral issues, or tendonitis.
Knee Pain
What starts at the hips affects the knee. Tight hip flexors can internally rotate the leg, shift the kneecap out of its groove, and unevenly load the tendons and ligaments that stabilize the knee.
Foot Pain
Tension around the hips affects leg mechanics down to the foot, where it contributes to overpronation. This can increase strain on the plantar fascia, load the heel unevenly, and shift pressure onto the big toe joint.
Lower Back Pain
A tight iliacus pulls the pelvis forward while the psoas tugs the spine into a downward, rotational compression that loads the lower back joints, discs, and surrounding muscles.
SI Joint Pain
Iliacus tension can tilt the pelvis forward into an anterior rotation, while an overworked piriformis reacts by pulling on the sacrum, increasing strain on the SI joint.
Sciatica
Tight hip flexors affect the alignment of the spine, which can contribute to nerve compression or disc issues that cause radiating nerve pain. In reaction to this tightness, the piriformis becomes tense and can further compress the sciatic nerve.
Shoulder Blade Pain
Tightness in the pec minor (chest) pulls the shoulders forward, while the muscles between the shoulder blades fight to pull them back, creating a constant tug-of-war that strains the upper back.
Upper Trap Pain
The upper traps tighten with stress and poor posture, and rounded shoulders with a forward head position only add to the load, keeping them locked in tension over time.
Glute Pain
Tightness at the front of the hip creates reactive tension at the back of the hip, causing the glutes and piriformis to tighten and develop a dull, achy pain.
Thigh Pain
A tight iliacus can irritate a nerve along the front of the thigh, causing burning or tingling, while also creating tension in the quad muscle that leaves the thigh feeling heavy or overworked.
Outer Hip Pain
An anteriorly tilted pelvis creates compensatory tension in the piriformis and TFL muscles, which attach near the outer hip. Constant pulling irritates the bursa and the adjacent IT band, leading to outer hip pain.
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 muscles is resolved first, everything else finally works the way it should. That's the piece that's been missing.
