IT made for great TV, but filming National Geographic's Limitless with Chris Hemsworth proved to be quite the challenge for the Thor actor.

Chris, who joined the Marvel Cinematic Universe in 2011, says the first series "almost killed me emotionally and physically", and he was very much a "guinea pig" thrown into various situations.

But the 41-year-old Australian adds that after each challenge, there was always "this kick, elation and rush of endorphins" that would give him a sense of achievement.

It's what encouraged him to do it all again.

The upcoming second series, Limitless: Live Better Now, sees The Avengers star discover how we can all live better - starting from today.

Chris tackles three high-stakes challenges with a focus on brain power, risk and pain. Across the three episodes, we see him pushed both mentally and physically.

He learns how to play the drums before joining Ed Sheeran onstage at a stadium packed with 70,000 fans, in Bucharest, Romania.

Then, inspired by how carefree and risk-tolerant his children are (he has a daughter, India Rose, 13, and 11-year-old twin sons Sasha and Tristan, with actress wife Elsa Pataky, 49) Chris climbs a 600ft Alpine dam in the Swiss Alps.

Chris also confronts his chronic back pain and immerses himself in a series of savage Special Forces trials.

Ahead of the series hitting our screens, the actor discusses how he approached the challenges and the instant ways we can all sharpen our minds and strengthen our bodies.

You team up with scientists to take on these epic personal challenges. What made you want to come back and do it all again?
