In one of Stacey Bell's Iyengar yoga classes, her teacher introduced her to wooden dowels with makeshift padding to support her back, neck, and shoulders to properly lift the trapezius muscles in Headstand. As the class tried the dowels first in Dolphin Pose, she felt an immediate release of tension in her trapezius, decompression in the cervical spine, and relief from TMJ she had been experiencing.
Sold, she made her own makeshift set and introduced the wooden dowels to her private yoga clients and even non-yogis. Her secret to nixing neck pain spread, and she acquired a business partner. Thus, Krikstix was born.
The versatile prop can be converted to one or two pieces and used not only to refine alignment in inversions but also to provide feedback for the body to deepen into asana. And bonus, it also works like a foam roller to therapeutically release fascia. Check out all it can do.
