    How the Matrix Works

    Prolonged sitting tends to create predictable length-tension patterns depending on how you hold your body. This tool maps common desk postures to general muscle groups—not a diagnosis, but a starting point for targeted resets.

    Each protocol takes roughly two to three minutes and can be done at your desk. Move slowly and stop if anything feels uncomfortable.
