The 6"5' Samoan giant has had a busy 12 months, working on no less than nine movies in the last calendar year. But that hasn't stopped the 46-year-old from keeping up his gym routine.
It wasn't easy though. Taking to Instagram, the Jumanji star shared a picture from his strength and conditioning coach about difficulties of keeping up his prime physique.
"Hard to really understand how challenging nuances it takes holding a 'peak muscularity' look for extreme action sequences that last all night long and two consecutive days straight in the hot sun. Every minutia detail is communicated between us constantly.
It’s all part of my commitment," explains Rienzi.
"I nuanced the peaking for these scenes by combing carb depletion, carb loading, water manipulation, mineral monitoring while working within the constraints of the elevated temperatures of the day shoots. It’s a fine line to balance holding a peak while filming intense physically demanding fight scenes. Consistent communication and monitoring is required."
Joined by Jason Statham, the new edition to the franchise follows Diplomatic Security Service agent Luke Hobbs (Johnson) and Deckard Shaw (Statham) who team to to take down the villain played by Idris Elba.
The movie comes out this year on August 2nd and is the 10th instalment of the long-running series.
