The training loop

ONE SYSTEM THAT GETS SMARTER AS YOU USE IT.

The tools are designed to work together. Your journal can update your map, your map shows what needs attention, and your strength plan supports the work you do on the mats.

  1. 01

    Map

    Mark what is in your game and expose the missing pieces.

  2. 02

    Log

    Capture what actually happened in class while it is fresh.

  3. 03

    Train

    Follow strength work that respects your time on the mats.

  4. 04

    Adjust

    Return with better information and choose the next focus.
