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.

The episode is a journey through the human gut and the process of turning food into energy to keep the body going. Humans have turned eating into culture, a way to celebrate our roots, to bring us together. But food is really just one thing: Fuel. It's where you get the power to live your life. Even when you're sitting completely still, your body needs a lot of energy to stay on. But nowhere is the need for fuel more apparent than when you push yourself to the absolute limit. And the microbiome, the bacteria living in our gut, plays a great role in all this.

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.

This eye-opening documentary puts a simple but provocative question to the test: how much does what we eat really shape our bodies and our health? In a tightly controlled scientific experiment, identical twins adopt radically different diets and lifestyles for eight weeks, allowing researchers to isolate the impact of food itself. By combining cutting-edge science with deeply personal experiences, the series reveals how diet influences everything from energy and metabolism to long-term wellbeing.
In the first two episodes, the experiment begins as each pair of twins commits to either a plant-based or an omnivorous diet. As they adjust to unfamiliar routines, some changes feel surprisingly easy while others expose cravings, doubts, and unexpected challenges. Along the way, questionable dietary advice is put under the microscope, and a celebrity chef rethinks his approach to cooking, highlighting how habits, culture, and taste all collide when science meets the dinner table.
