Knox Jolie Pitt and Chris Hemsworth have something in common. Despite their age gap and the fact that both lead different lifestyles, over the past couple of years, Knox has been developing an interest in fitness and maintaining his health, showing some impressive muscle growth and a penchant for a sport that Hemsworth and many other Hollywood stars have taken up.
The sport is Muay Thai, a martial arts combat sport known for its intense full-body contact, requiring practitioners to use their elbows, knees, shins, and fists to take down their opponents.
Over the past year, Knox has been photographed attending his Muay Thai lessons, with him gaining plenty of muscle definition. He's also competed in Muay Thai tournaments, showing his commitment to his sport.
His steady progress has sparked curiosity among fans of the Jolie-Pitt family, especially since Knox has largely stayed out of the public eye compared to some of his siblings. Those who’ve followed his journey have noticed his discipline often arriving early to training sessions and engaging enthusiastically with his coaches. He also supplements his Muay Thai workouts with outdoor runs, which he's been photographed participating in in different areas of Los Angeles.
In July of this year, Knox participated in the Born to Win Combat Sport competition hosted the day after his birthday. The competition was hosted in Los Angeles, where he ended up taking gold, according to various posts on social media from his Muay Thai academy. He was supported by his sister Vivienne and his mom Angelina Jolie, with the two cheering him on from the stands.
Chris Hemsworth's Muay Thai experience
Muay Thai has become an increasingly common sport in Los Angeles, practiced by many Hollywood stars. In the case of Hemsworth, he's used the practice to develop the strength and flexibility required for his action stunts and for his Thor physique.
“Now I add in a lot of other sorts of movement, flexibility, and functional training,” said Hemsworth in an interview with Men’s Health. “Bulk is nice, but being more agile is definitely important.” To develop his other muscles, he said he practiced, "A ton of boxing or Muay Thai workouts. I surf a ton, and I do a lot of yoga, too.”
Hemsworth isn’t the only actor drawn to the sport’s intense discipline and conditioning. Stars like Tom Hardy, Halle Berry, and Jason Momoa, who are all known for their committed performances in action films, have all incorporated Muay Thai into their training routines, using it to improve coordination, stamina, and on-camera fight skills. The sport’s blend of cardio and strength makes it a natural fit for actors preparing for demanding roles.
