Anchor is the point where the practitioner pins the muscle before asking for resistance.
In 📝Resisted Soft-Tissue Release the anchor is a fulcrum, not a bruise. The press lives there while the client works. It is not a joint adjustment and not a claim a structure is being held in place. Sharp, numb, or panicky under the contact is a stop.
Clients feel a precise hold. The limb then works against that hold.
