Kris Gethin was born on a farm near Builth Wells, Wales, and was never into his fitness growing up. But he was always active and took things to another level when he studied international health and fitness in the mid-Nineties.

This got him interested in building muscle and performance which prompted him to leave Wales for the US in 1999.

Since then he has worked numerous jobs including as a personal trainer in India, Australia before returning to the US where he currently lives in Boise, Idaho.

While his initial focus was on building muscle and improving performance, Kris’ current drive is on delaying and even reversing his biological clock.

And after seeing the effect that Alzheimer’s had on his grandfather John Morgan before he died aged 92 in 2019 – he is determined to remain healthy and independent for as long as possible.

“I want to be hiking up Snowden in my 90s.

“I’m very close to my family and I’m closer to them now even though I live so far away. It’s all about quality rather than quantity. I want that to continue.

“I don’t want to be in a retirement village, I don’t want to be on a zimmer frame, I want to be independent.

“I’m going to do everything I can to make sure that happens.

“I love weight training, running, swimming and mountain biking. I don’t want to watch from the sidelines. I want to be part of it.

“I believe that having a young mindset is key. I set my intentions every morning and think of myself as a 25-year-old – which is my biological age.”

Kris says he also keeps young by adopting a “shotgun approach”.

This involves only eating grass-fed, organic, wild-caught meat.

He is in bed by 7.30pm every night and has various youth-boosting drugs injected into his body every six weeks.

He also drinks hydrogen-rich water every day because it is high in antioxidants, he said.

He has an infrared sauna every day followed by a three-minute ice bath which he says improves his mental stability.

In addition to this, he recently had 600 million stem cells injected into him at a Colombian clinic.

His extreme regime may not be for everyone – but Kris says that it is never too late for people to turn things around.

He said: “It’s never too late to turn it around. My father is in his 70s and he goes mountain biking every weekend.”
