Dynamic duo set to ignite a new era in health and ageing

A local duo, inspired by their own health challenges are on a mission to redefine ageing as a time of strength and power, with the launch of their groundbreaking health and fitness venture. Founded by health and fitness expert Sam Guest and medical scientist Dr Hannah Beaumont, Promethean Longevity offers a science-driven, personalised approach to reclaiming vitality and extending health span.

“We all know our chronological age—our birthday—but our biological age reflects how well we’re truly living,” explains Dr. Hannah Beaumont. “Poor diet, stress, or inactivity can age us faster than we realise. With personalised, science-backed coaching, we’re helping people turn back that clock—sometimes by decades, and in only 6 weeks!” One early participant even slashed their biological age by 17 years, a testament to the programme’s power.

In Yorkshire, where life expectancy lags 2.5 years behind the national average—and women face a stark 7-year gap compared to Kensington & Chelsea—Promethean Longevity is on a mission to improve the health span of Yorkshire residents.

Sam and Hannah’s own health struggles has fuelled their vision: Sam rebuilt himself after burnout collapsed his extreme sports business, while Hannah overcame teenage autoimmune disease with her dedication to scientific knowledge and lifestyle changes. This has led to the duo combining science and passion to empower people to live stronger, longer.

The team have developed their own science based algorithm which gives participants their biological age before embarking on their flagship 6-week ‘Stealing Fire’ programme. Grounded in evidence-based coaching, they are already seeing remarkable results, with one participant reducing their biological age by 17 years.

“Health isn’t a luxury—it’s the foundation of a life well-lived,” says Sam Guest, “We’re here to challenge the idea that decline is inevitable as we get older. This isn’t about quick fixes. Our evidence-based programme uses science and support to help people thrive at any age.”

The pair will host an official launch event Wednesday 14th May members of the public are invited to attend for free. Held at Sancta Cafe, Otley they will unveil the brand’s flagship 6-week programme which is designed to add at least 6 years on to the health span of participants. From 6:00 PM to 8:00 PM, guests will experience live demonstrations, hear from founders Sam and Hannah, and meet the community already transforming their lives with Promethean Longevity.
