It reminds me of an interview I saw with Alan Richardson (?), the guy playing reacher on the Amazon series. It was in support of the new season, but basically the conversation revolved around how exhausting it was to maintain the required physique for the role, and how it meant he couldn’t do some of the things he normally enjoyed—he was too heavy to run without impact injury, and flexibility and reach was an issue.

I’d imagine transitioning between these physiques can probably be challenging and taxing on the body as well.
