Coaches and managers of team sports have used practice film as a teaching tool for as long as the technology has been available and for the simple reason that there’s no better way to judge performance and prepare for competition. And let’s face it, nowadays, you don’t need to invest in expensive AV equipment in order to record yourself, you need only your smartphone and someone to tap the little record button.

Video coaching can be useful because, even when a trainer is telling the fighter that they’re dropping their left, until the athlete sees it for themselves from a different perspective, the message may not sink in. Watching the action from the outside allows the athlete to understand the issues that are present in a way that is vivid and sometimes unexpected.
