For a martial artist wanting to have a good insight into their progress it is necessary to regularly measure and evaluate their training performance. Unfortunately, most of today`s performance tracking devices applicable in martial arts training are expensive and thereby available only to professional sportsmen.This paper describes the model and prototype implementation of a device which facilitates information gathering and automated feedback provision during or after a heavy bag training session. Its main features are measuring relative punch strength, frequency, and spatial distribution with a minimalist setup and affordable hardware components. Device prototype implementation is evaluated in authentic settings and shows promising results.
