Static platforms

A set of identical low boards designed to stack together for adjustable plyo and step-up training. A single board works as a sit platform; two or three stacked become a hindquarter-loading step. Per-board geometry follows the same rule as a place board (width to the hock points, length to body type). The modular alternative to a fixed graduated plyo set — more flexible, easier to transport, slower to set up. Stack height follows the standard plyo-height progression once that research has been finalised.
