Gripcount: a solo jiu-jitsu movement atlas

Field notes

The curriculum divides 36 studies into six positions and six groups, separating single movements from linked chains, recovery work, and conditioning. A study can show a draggable model, five phases, three faults, and half-speed playback; the site says 33 studies need only a padded mat, while others call for a notebook, partner, or coach.
