What if you could combat aging and discover the full potential of the human body? Global movie star Chris Hemsworth, despite being in peak superhero-condition, is on a personal mission to learn how to stay young, healthy, strong, and resilient. Undergoing a series of epic trials and extraordinary challenges in order to understand the limits of the human body, he'll learn firsthand how we can live better for longer by discovering ways to regenerate damage, maximize strength, build resilience, supercharge memory and confront mortality.
Ever since his teenage years, stress has been part of Chris’s life, and he wants to learn how to deal with it better. Psychologist Modupe Akinola challenges him to stay calm during a terrifying walk along a crane that’s projecting out from the roof of a skyscraper. Modupe will train Chris in powerful physical and psychological techniques we can use to control the stress in our lives and combat the risk it poses to long-term health.

To maximize longevity, you might think it’s best to play it safe and stay cozy. But some scientists believe we should do the opposite, as exposure to extreme temperatures can trigger our bodies’ own defenses against the killer diseases of old age. Chris heads for the freezing Arctic with his brothers Liam and Luke to take on the ultimate cold therapy.

Chris turns to longevity doctor Peter Attia to find out how changing his eating habits can help his quest for longevity. Ironically, the answer is to eat no food at all for four long days. If he can bear the hunger, fasting will unlock his body’s own anti-aging powers and give Chris the edge he needs when he tries to hunt for his next meal … by spearfishing off the Great Barrier Reef.

As Chris bulks up for ‘Thor: Love and Thunder’ he needs to build a body that looks right for an immortal god. But, he also wants the kind of muscles that are scientifically proven to help him stay strong and healthy as he grows older in real life. Teaming up with extreme sports guru Ross Edgley, he trains for a grueling 100-foot rope climb challenge, changing him from an ornament into an instrument.

The series explores the incredible universe inside each and every one of us. Through an examination of diverse personal stories from around the world, Human reveals how our everyday lives, our passions, and our goals are powered by the amazing systems that define our biology as a species.
The first episode goes on a journey with parents who are preparing for new life to see how our bodies create and sustain new life. Through their stories we learn about what is fundamentally shared and absolutely unique about the experience of birth.

What's behind a pulse? The second episode dives into the world of an ice climber, a bus driver, a woman in labor, and a senior dance club to show how the human heart and the circulatory system power our physical and emotional lives, and create the pulsing rhythm of our world.
