Sharing the details of training sessions that happened behind closed doors has always been a common practice in the pre-fight build to any fight. Coaches and sparring partners offer effusive praise, recounting blistering performances and new levels of conditioning while suggesting, as always, that their fighter has never looked better.
In recent years, those details have flowed more freely and come with extra seasoning in instances where the training partners turn into opponents. Whoever got the better of things makes sure to make it known, offering up colorful recollections of knockdowns and knockouts or dominant grappling performances, occasionally going as far as to offer up a sizzle reel or grainy clip from the session in question.
