Jude Law has built an impressive body of work over his career (see: Gattaca, The Talented Mr. Ripley, and Sherlock Holmes franchise), but he isn’t traditionally known for having an imposing physique. So to build an impressive body of work, quite literally, for his role as a British Secret Service agent in The Rhythm Section, he turned to trainer Johnny Silmon.
He put Law through an eight-week bulking phase, followed by 12 weeks of functional work with kettlebells and hammers to first broaden and bolster his 5’10” frame, then forge the power, endurance, and agility required of an agent. Try a sample workout from the bulking phase: The Triset Workout That Transformed Jude Law Into a Secret Service Agent.
Silmon also has an extensive background in the Indonesian martial art of pencak silat (characterized by artistic elements and self-defense), so occasionally their training days included grappling and sparring.
