Looking back at classic movie physiques, Pasternak’s ideology is fairly commonplace. With the exception of Stallone, Lundgren and Schwarzenegger, prior to the early 2000s, action stars were rarely muscle-bound animals. In fact, the focus was primarily on lean muscle and posture, helping to strengthen the foundation of mobility and poise without needing actors to pile on a bunch of muscle. This, in turn, allowed for greater results in a shorter timespan and reduced the likelihood of overtraining. Pasternak explains the biggest challenge working on franchises like Jumanji and Fast and Furious was ensuring the actors got the little things right.
