In the high-stakes world of competitive powerlifting, mild-mannered accountant Arthur, played by Josh Gad, finds his orderly life upended when he is unexpectedly thrust into the spotlight as the unlikely coach of a rebellious, undisciplined prodigy. Directed by Rhys Hayward, this raucous comedy pits Arthur's love for meticulous spreadsheets against the chaotic, chalk-dusted reality of the gym floor, forcing him to confront his own limitations in a sport built on sheer force of will. As their mismatched partnership careens through grueling training montages and outrageous public spectacles, Arthur must dig deep to find a strength he never knew he possessed, all while trying to prevent his volatile charge from self-destructing before the national championship. With sharp wit from writers Dan Hernandez and Benji Samit, Heavy Duty delivers a hilarious and surprisingly heartfelt underdog story about the weight of expectation and the unexpected bonds forged under the iron.
