Why the Mark is right for you.

Fixes lower back & hip issues

Strategize your route to recovery.

Eliminate your pain by targeting its cause. A tight iliacus jeopardizes the health of the spine, hips and pelvis. In treating one muscle, you prevent weakness, tightness, and discomfort in all the rest.

Solves for sciatic nerve pain

The cause of pain isn’t usually where you feel it.

Your tight iliacus and psoas muscles pull your pelvis forward, making muscles in the back of your hip react by tightening up too. Stretching your piriformis is futile when you aren’t addressing why it’s tight in the first place.

Alleviates hips that make you feel stuck

Move purposefully, not painfully.

Relaxed hips restore overall body function and symmetry. You can increase your mobility, strength, and flexibility by targeting the muscles that matter. Regaining your full range of motion will allow you to optimize movement and eliminate joint wear.

Targets pain at its core

Don't ignore the most crucial muscle for full body health.

Relaxing your iliacus not only stabilizes your hip and spine, but it aligns your pelvis. When your pelvis is misaligned, all of your joints from your hips to your toes and from your SI joints to your head, will be rubbing the wrong way. Releasing your iliacus gets right to the root of it all.

Eliminates pain in 90 seconds

Heal effectively and efficiently.

Before the Mark, your iliacus muscle was nearly impossible to target without a skilled therapist. Now, all it takes is 90 seconds a day to release accumulated tension and remove pain. No other tool on the market can target like the Mark.

Gets you back to your true state

Start your journey to the optimal.

Like a flick of a domino, a relaxed iliacus and psoas allows for the rest of the muscles and joints in your body to strengthen and align. Your body is one step away from its ideal state – the way it was meant to be.

Frequently asked questions

How does the Mark differ from other hip flexor or psoas release tools?

Other tools on the market focus only on the psoas muscle, but do not address the iliacus muscle at all. For best results, you need to treat both muscles.

The Mark was designed by a physical therapist to access both the psoas AND iliacus muscles, making it the most effective tool to release your hip flexors.

The size and shape of the Mark’s tip replicates a skilled practitioner’s fingers, allowing it to penetrate deeper into your muscles and with more precision than other tools.

Press into the psoas with the tip straight up. Access angles that you could never reach before by pressing down on the handle to rotate the tip of the Mark. This is how you get to the iliacus.

What is the difference between the psoas and the iliacus muscles?

Your hip flexor is made up of the iliacus and psoas, which are intimately connected near the hip, but are still two separate muscles. These muscles perform similar, yet different functions in the body. They also have different attachment points and are innervated by different nerve roots.

If there is tension in one, there is likely tension in both. Releasing tension in one but not the other will lead to short-term results. For the best and longest-lasting results, you should be releasing both your iliacus and psoas muscles.

Can't I just use a lacrosse ball?

No. A lacrosse ball is not big enough to reach the psoas or the iliacus. While a larger ball may be able to reach the psoas in a diffuse way, it still will not be able to target the iliacus on the inside of the pelvic bone.

The patented design of the Mark allows for firm, direct, and precise pressure to both the psoas and iliacus muscles from many different angles.

Once you try it, you will find that it is able to target the psoas and iliacus in a way that no ball or other self-release technique or tool can.

Will the Mark address my pain?

Tension in the iliacus and psoas muscles can have a huge impact throughout the entire body because it can twist your core affecting not only your back and hips, but your lower and upper body.

The Mark has helped thousands of people overcome:

- Lower back pain
- SI joint pain
