Chris Hemsworth revealed that drumming for Ed Sheeran was his most difficult challenge on his National Geographic series Limitless: Live Better Now. In the season premiere, Hemsworth had just months to learn the drums and perform live in front of 70,000 fans in Bucharest. He admitted, “I can do intense training, extreme cold, fasting, all of that, but learning to play the drums was way out of my comfort zone.” Despite initial struggles, Hemsworth embraced the challenge, showing the importance of pushing personal boundaries to enhance brain health.
