We help busy professionals and expats in Phuket build lean, strong, capable bodies while losing body fat and optimising their health - so they look, feel, and perform at their best for life.
Backed by over 20 years of combined experience across fitness and medicine, our coaching combines sustainable habits that fit real life with real medical data that proves it's working. Because the goal was never just to lose weight or gain muscle - it's to build a body and a lifestyle that will serve you for the next 10, 20, and 30 years.
A short walkthrough of exactly how we take you from where you are now to where you want to be - and why it works.
Ever had blood tests done, been handed a page of numbers, and had no idea what to do next? We turn your results into a clear, actionable plan and build your coaching around the 23 hours a day you're not in the gym, because that's where your results are really made.
Through weekly webinars, daily educational videos and ongoing coaching, we teach you the why behind every recommendation. Our goal is simple: to give you the knowledge and confidence to manage your health long after coaching ends.
Finally understand nutrition so you can make confident decisions long after coaching ends.
Build a body you're proud of - aesthetic, strong, and built to last.
Build daily habits that become your lifestyle, so you can perform at your best every day.
Optimise your health from within.

I've been working with Kristian now for a little over three months and, wow - I'd like to say it's still the beginning of my lifelong journey. I've learned structure, how to eat, discipline, and most importantly, obviously, accountability. And when you see the gains actually happening, it's so motivating.
What I can tell you is the guy knows what he's talking about. Like I said, I've been on a lot of different little plans here and there, but he really has the knowledge. And if you follow it, you'll get results. That's all I can say. He makes you accountable, super nice guy, super easy to work with. And actually, I love the guy. He's great.
If you have any hesitation - I did - research it, talk to him. It works, it really does. You meet every week, he's super accessible, we do weekly accountability. It's great.”
data-yt (9:16)“We went for 10 kilos of weight loss, and I'm currently on 12!
Hiya, I'm Katinka, I'm from the Netherlands. About half a year ago I decided I wanted to lose some weight.
So we agreed to try and make me lose 10 kilos. Well, I'm a busy girl. I work a full-time job. I have a family of 5 kids. It's not that easy to find the time. There are a few challenges, but you know - Kristian made a personal plan for me. The kilos started flying off very fast, to be honest. And every week, we would go over the stats and see how we could tweak it so we could do a little bit better.
What I personally love about his coaching is that he is just as invested in it as you are - if not more even! So I'm still going good, and I feel great.”
data-yt (9:16)“My advice to those people who are considering signing up is just to do it. You have everything to win from it, so go for it!
Before I started working with Kris, I was lacking consistency. For 3 months I was in a fat loss phase, where the main focus was to lose body fat, to get as lean as possible. Now that I've achieved that, I've switched over to a muscle building phase, where the goal is to build as much muscle as possible.
So what I've learned during this process is how to stay consistent and how to be able to live a healthy lifestyle in a day-to-day basis, basically. I've achieved a lot. I have achieved amazing results in the gym, strength-wise and also physically. The changes that I've seen is that I've lost a lot of body fat and I've gained muscle. I have better technique, how I do the exercises, in a way more safer way.”
Deep dive into how the Phuket Performance Health system produced each result - the starting point, the strategy, and the outcome.
Starting point: As a hostel manager, Carol lived in a social world where nights out and drinking were part of everyday life - and from day one she was clear she had no intention of giving that up. But her health had slipped down the priority list, and the reality hit when she came home one summer and could no longer fit into her old clothes. She needed an approach that worked with her lifestyle, not against it.
The strategy: Instead of banning social events or alcohol, we built a plan around Carol's real life - structure around her nutrition, strength training and daily movement, and the skills to enjoy nights out without undoing her progress. Alongside the physical work, we focused on consistency, sustainable habits and the mindset to make healthy choices feel natural rather than forced.
The outcome: Over 16 months, Carol lost 37kg of body fat and built serious, visible muscle - she is now known at work as "The Terminator" because she out-lifts most of her male colleagues. The transformation went far beyond the physical: more energy, more confidence, greater strength and better long-term health, wrapped in a lifestyle she can maintain for life.
Starting point: As owner and head chef of Surf & Turf by Soul Kitchen, long hours, high stress and the relentless demands of running a busy restaurant left little room for structured nutrition or training. Burnout was starting to show - flagging energy, poor focus and steady, unwanted body-fat gain.
The strategy: We built a flexible, high-protein nutrition plan that fit around his unpredictable kitchen schedule, paired with a strength-focused training programme designed to rebuild performance, energy and recovery. Consistent accountability and regular adjustments kept him on track through work pressure and travel without missing a beat.
The outcome: In just six months he lost 15kg of body fat, built lean muscle, and regained the energy and confidence to perform both in and out of the kitchen. More importantly, he now has a sustainable system that continues to support his lifestyle and his career as a busy chef.
Starting point: As a busy mum juggling two children, a full-time job and the demands of everyday life, Josefine constantly put everyone else first - her own health always came last. She wasn't looking for a quick fix; she simply wanted a realistic way to lose weight, improve her health and feel like herself again, at a pace she could sustain.
The strategy: Rather than overhauling her whole lifestyle at once, we started slowly - first focusing on structured nutrition, building up her daily steps, and learning how to navigate social occasions without undoing her progress. Once Josefine found her rhythm with meal prep and calorie banking, everything became far more manageable. Strength training was just the sprinkle on top - but she stayed consistent.
The outcome: Over the course of a year, Josefine lost 25kg while building habits that fit her real life. She's now moved into maintenance with the confidence and knowledge to sustain her results long term. More importantly, she proved that even with a full-time job and two children, it's possible to prioritise your own health without sacrificing the people who matter most.
Starting point: As the CEO of multiple businesses, Ged already had a strong foundation - years of training and looking after his health meant he was neither overweight nor unfit. But he wanted to go further: strip away the final layer of body fat, reveal the muscle he'd worked hard to build, and optimise his health from the inside out. With a demanding schedule, he needed a plan that fit around real life.
The strategy: We built a sustainable system around Ged's lifestyle, pairing progressive strength training with strategic calorie adjustments across each phase, alongside a focus on sleep, stress management and recovery. Through weekly coaching, accountability and education, Ged understood not just what to do, but why - so he could stay consistent without relying on extremes.
The outcome: Over 11 months, Ged lost 12kg and completely transformed his physique through body recomposition. Beyond looking leaner and more muscular, his internal health improved too, with positive shifts in his lipid profile, ApoB and IGF-1 - proof that true transformation is about optimising your body inside and out.
“I have a very clear goal to lose weight, and I'm happy to feel that I'm on the right track. It's not only about food, it's also the movement, the training, and the fact that this process is going to take me to a different place in life. That's exactly what I needed.”
“WOW, thank you SO much for taking the time to explain everything! I will never stop singing your praises. I swear all of my friends and family know how incredible you've been in this journey and I can't picture having done this without anyone else. You are seriously the best in the game and I'm SO thankful to have had an incredible coach 🙏🏼🙏🏼🙏🏼. Life changing experience!”
“I LOVE this new way of life. I love that I'm forward thinking and weighing up what I'm eating rather than just grabbing whatever I feel like. I love how much I'm walking. I love how easy it feels. I love how I'm feeling. THANK YOU for helping me improve so many areas of life with this. I can't wait to see how far we can take it 😁.”
Phuket Performance Health exists because lasting health needs both sides of the equation: world-class coaching to change behaviour, and real medical insight to know it's working.
Kristian has been in the fitness industry for over 15 years, specialising in sustainable fat loss, strength development, and helping people build a lean, athletic physique that not only looks great but also performs in everyday life.
Being active has always been a big part of his life. He spent his teenage years skateboarding at a high level before moving into martial arts and working as a certified ski, snowboard, and mountaineering instructor in Norway. In 2010, he discovered CrossFit, where he became a CrossFit Level 2 Trainer and competed internationally as an athlete.
It was through CrossFit that Kristian discovered his passion for coaching. Seeing how training and lifestyle changes could completely transform someone's confidence, health, and quality of life inspired him to dedicate his career to helping others.
After more than a decade of coaching clients in person, Kristian realised something was missing. Seeing clients for just a few hours each week wasn't enough. Lasting results didn't come from one hour in the gym - they came from the other 23 hours of the day.
That realisation led him to create KristianKFitness, an online coaching platform built around the belief that lasting transformation comes from the habits and decisions made outside the gym. As the business grew, he partnered with Dr. Jan to expand the company's approach beyond fitness alone.
Today, KristianKFitness is the parent company of Phuket Performance Health, combining expert coaching with medical expertise to help clients optimise their health from the inside out.
Dr. Jan is a medical doctor who earned her MBBS from the UK. She also holds a Bachelor's degree in Biochemistry and a Master's degree in Cancer Research, giving her a strong scientific foundation in understanding human health at both the molecular and clinical level.
After qualifying as a General Practitioner when she relocated back to Thailand, Dr. Jan's passion for preventative medicine and longevity led her to pursue further qualifications in wellness medicine at Dhurakij Pundit University in Thailand. Rather than simply treating disease, her focus is on identifying risk factors early and helping people optimise their health before problems arise.
Dr. Jan believes in healthcare, not disease care. Her philosophy is that good health starts with mastering the fundamentals - nutrition, movement, sleep, recovery, and understanding how the body works. By combining lifestyle medicine with detailed blood analysis, she helps people make informed decisions based on what's happening inside their body, not just what they see in the mirror.
Working alongside Coach Kristian, Dr. Jan brings a medical dimension to the coaching, ensuring clients don't just look better and perform better, they become measurably healthier from the inside out.
