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 replicate a skilled practitioner’s fingers, allowing it to penetrate deeper into your muscles and with more precision than other tools.
