Sustainablefitness Reviews 

I joined Sustainable Fitness as a complete beginner, mainly just wanting to lose weight, but I’ve ended up getting so much more out of it. Now 6 months in to the programme I’m still amazed at the results I’m getting.

When I first started, I didn’t even think I’d last a month. With everything else going on in my life, I couldn’t see how I’d manage to stick to it. But that’s what surprised me most, it actually fits around busy family life.

So far I’ve lost 3 stone, which I’m really proud of, but the biggest change has been how I feel in myself. I’m more confident now, and it’s a nice feeling getting regular comments about how well I’m looking, it definitely keeps me motivated.

The support and accountability have been a huge part of it for me. The coaches are always there if you need help, a bit of encouragement, or to keep you on track, and the community is amazing too. Being around other people who are on their own journeys really helps keep you going.

My life is pretty busy, I’m an aircraft engineer working shifts and I’ve got two young kids, so I needed something that would actually fit around real life. There’s no pressure to be perfect, just to stay consistent, which has made it much easier to stick to.

It’s changed a lot more than just my weight. I feel better, more confident, and just generally happier in myself. Definitely one of the best decisions I’ve made.

As someone who has not taken proper care of themselves, both physically and mentally sometimes, and now has a job role that means I sit behind a desk, rather than being out on the tools as a front line engineer. This program and company has, long story short been incredible. Through out personal turmoil and a struggle to hold myself to higher standard of self care. The company and the coaching staff, have simply been incredible. Life can be both challenging and simple, and these guys really help make the challenge seem incredibly simple. When I've lacked discipline or focus, they've bought me back to the clear goal, of making my life better. It is not often in a buisness to customer occurrence, that you have such incredible support and guidance. It is one of those rare occasions where you feel that the coaching staff are always fully behind you and on your side, whilst also holding you accountable for your own jounrey. Allowing you to feel heard and supported and not there for the cheap money grab, like some can be.

Because of Coach Dan, I now feel confident in my journey and myself in it. Finally found a coach I can trust and be fully open with. Knowing my commitment to myself and the program is reflected in his commitment to help me too.

I would highly recommend anyone to give these guys a chance. Whilst they in turn give you chance, that you may not be giving yourself.

I highly recommend Aviation Health & Fitness! If you are reading these reviews, reach out to Darren, take the plunge, and join this amazing program!
I joined the program in January and it's been a great journey so far. I'm in my late 30s and I've been struggling with my weight for the past few years.
With the support of my coach Rob, I've dropped 7kg so far and shifted my mindset on weight loss. The team have created a flexible eating plan that works around your life whilst the coaches provide ongoing support, motivation and accountability. Once you immerse yourself in the program, it really is the ticket to success for your well being.
My job as a pilot brings volatility to every aspect of routine. I'm travelling, living in hotels, training, working through the nights etc. The program has helped provide a framework to follow no matter what the roster throws at me! I've continued to go on holidays, enjoy nights out with the lads and still see results.
I'm looking forward to the rest of the year and seeing where this program takes me! Trust the process, it's excellent.

Darren, Rob & the team are great! I highly recommend the team at Aviation Health & Fitness to anyone in the airline industry. No matter how busy I am flying and outside of work they tailor everything to work for me!

I am a tech services engineer, i was with Darren and Dan for the past year and learned so much from them. I was finding it hard to gain muscle and size before joining the programe. After a year i have gained over 8kg of muscle. Feeling alot better on myself, fitter than ever, better shape then ever. The programe thought me alot over thr last year such as dieting, consistency, responsibility etc. Darren and Dan were always at the end of the line to answer any questions i had and everyone involved were so helpful. Would highly recommend the programme to anyone.

For anyone in Aviation, if you feel like you're at a dead end with trying to fit fitness and health around your job, I cannot encourage you enough to get in touch with the team. It will change your life, and you won't look back.

The guys are simply built different. Dan, Darren, and Rob are 100% understanding and supportive of everyone's unique situation and I say that because I know first hand. Major health factors, travelling 75% of the month on average, hotel living, confidence - they've been with me every step of the way, and we're only just beginning!

I work as an aircraft maintenance technician for a major airline, so to say that my schedule can be unpredictable at times would be an understatement. Bad hours, varying shifts, weekends, holidays... Check! These guys understand this as they've been there and know how we work in this career field. Working with Darren, Dan, and Kristofer has really been a life changing experience. I was overweight and had very unhealthy habits which were in turn leading me down not the best of paths. This is a total lifestyle overhaul, and you'll learn how to take care of yourself properly; it's not just a diet plan. You'll never be hungry, you can be sure of that! These guys are total pros at what they do and I can't speak enough about how helpful, supportive, and encouraging they are; it's what I needed and I'm more than elated at the 20+ kg I've lost thus far. These guys have cracked the code! Just put in the due diligence and there's no way you'll fail!

I couldn’t be happier with the progress I’ve made with Sustainablefitness. Darren and his team are truly changing lives for aviation professionals around the world. This isn’t a fad diet or a trendy workout plan—they teach you a sustainable code to live by that promotes long-term health.

I’ve been in aviation for nearly 24 years and have lived the hotel life, the yo-yo diets, and the intense workout plans that lead to fast burnout. As I entered my 40s, I realized I needed real change—to reduce my “wing loading,” but without another unrealistic diet or workout routine that doesn’t work on the road. I needed a sustainable process and a healthier way to live while traveling. That’s exactly what Sustainablefitness provides.

They helped me crack the code to being healthy, feeling good, having energy, and losing weight. They reignited my motivation to work out and actually made me excited to get back into the gym. I’ve lost over 10 kg and am wearing clothes I haven’t worn in more than 15 years. I’m incredibly appreciative and thankful for their program.

If you’re an aviation professional looking for guidance on how to eat and work out while living the hotel life, I highly recommend reaching out to these guys. With your commitment and effort, they can educate you on how to live a healthier, more sustainable life on the road.

I can’t say enough good things about Sustainable Fitness and the lads i have been working with — Darren, Dan, and Chris. From day one they were incredibly supportive, knowledgeable, and genuinely invested in my progress. They go above and beyond to help you stay on track, answer questions, and make the process realistic and sustainable.

I’ve only been on the program for about two and a half months, and I’m already down 11.5 kilos, which just shows that the program really works if you put your mind to it. The guidance, accountability, and encouragement make a massive difference.

I’d strongly recommend Sustainable Fitness to anyone, especially those working in aviation. The guys understand the demands of the job and will do everything they can to help get you back into proper shape and proper health. If you’re serious about making a change, this program is 100% worth it.

Sustainable Fitness helped me find myself again. As an apprentice Aircraft Maintenance Engineer working night shift, the lifestyle I lived started to take a real toll on both my physical and mental health.

One day, while scrolling through Instagram reels, I came across some funny aviation posts. Little did I know that the man running the account would end up changing my life. After a lot of thought, I decided to join the fitness program. I was hesitant at first because I knew I would be the youngest and one of the few women in my field, but I was welcomed with open arms and an immediate sense of community. Working nights does not leave me with much of a social life, so getting to connect and share experiences with others in the group helped everything feel a little less lonely.

Darren introduced me to Coach Dan, and together they have been like guiding pillars of light throughout this new adventure. Starting was not easy, and it forced me to hold myself accountable in ways I never had before. Thanks to Dan and Darren, I have made so many positive changes. They are there every step of the way, offering guidance, support, and motivation, and also calling you out when you need it in a way that pushes you to become better for yourself.

It's like having a logbook for your life. Seeing everything written down shifts your perspective on how you are actually living day to day. Before this program, I did not feel like myself. I was eating my feelings, sleeping my days away, and constantly running on empty. Now, six months later, I am energized, eating well, sleeping better, and I genuinely feel like myself again.
I am excited for the new year and all the progress I will continue to make!

Great system, really works. Lost almost twice as much weight as I had initially targeted. Coaches bring the right balance of accountability and support. I found they had the answers for any road bumps I meet on the way. Thanks for everything Dan and Darren👍👍

Darren and the team at Sustainable Fitness have completely transformed the way I approach my eating habits. What sets this team apart are the coaches who not only talk the talk, but all walk the walk, and the daily recording of metrics — everything from calories to sleep. The platform makes it incredibly easy to track improvements, and seeing the data build over time is hugely motivating.

The real game changer is the follow-up, attention to detail and knowledge of the coaches Darren, Kris and Dan. It is genuinely personalised, not a one-size-fits-all template. Their feedback and coaching is timely, encouraging, specific, and actually useful.

For anyone in aviation who needs structure, accountability, and a holistic program tailored to the realities of our lifestyle, this is by far the best option. If you want to be the healthiest, best version of yourself sign up now!

Darren and Dan are great guys who go 5 extra miles for the people they help and have endless knowledge and experience to help exactly how and when you need it. Highly recommend them to anyone looking to take control of your health and fitness

Working with Darren and then with Dan has been a transformative experience. I am not infinitely more aware of the impact diet on everything. This business is perfectly name. It is set up for sustainable change.
If you're prepared to be challenged and prepared to do the work, this will deliver.

I’m a busy Mom, wife, and airplane mechanic and I had resigned myself to just being over weight. I’m 36 and in early peri-menopause and I had tried darn near every weight loss program out there! I’m just trying to balance 12 hour work shifts that were very high stress and exhausting and still present with my family with what little free time I have. The other programs I tried were just impossible to follow. Those programs either required me to spend endless time in the gym, which wasn’t realistic with my work shifts at all, or I was having to follow complicated diet plans that basically were just starving myself. It was so insanely frustrating! When I found Aviation fitness I was blown away that there was even a program out there that not only understood my crazy work/life balance but would work with all of that and not against it. The coach’s have been amazing and I cannot believe that I’m actually losing weight! I thought for sure I’d have to resort to giving myself weight loss shots but here I am, not even a whole month in, and I’ve lost 9 lbs! What’s been great too about Aviation Fitness is I find I’m not stressing about my meals and it feels like I have more time with my husband and son now! I don’t have to constantly think about “did I eat too much?” “I need to workout because I ate X, Y, and Z.” or whatever else. I cannot wait to see how I keep progressing! And I have better energy and better sleep too! I just feel healthier!

Super happy with Sustainable Fitness!
I saw that many of the results they were showing were of men and aviation professionals so I was hesitant at first because maybe i wasn't the right fit for the program's dynamic BUT let me tell you that since the moment i found interest, and even before, I felt i could trust 100% the team at sustainable fitness.
They were organized, professional and motivational and made me feel that the goal of losing 10-12 kg was easy instead of the blockage I had in my head where i thought that was already impossible and i had to give up on that idea. I have already lost kg's that i couldn't lose in the whole year before joining.

Coming from the IT sector less related to aviation i found myself constantly saying oh well maybe is not for me, older men dominated space in aviation and barely woman. But i saw one of the videos of a woman that lost so many kilos with them in an healthy way she looked super happy and healthy and thats how i want and im starting to look like.

You see how everybody cares of you, almost daily checkins, questions, friendly communication, organized approach (& works!)... many more things to say but this is already a big/long review haha

This isnt just a weightloss program as Darren says, they help you form habits in a fun way and adapting to MY lifestyle (in my case), so I feel less friction. Eternally grateful to having joined and to what's ahead. But if i had to repeat this decision of joining and being in this journey by the hand of the Sustainable Fitness team i would repeat it 10x.

BIG Thanks to Darren too for being the coach that comes and changes lives for the better! Big respect!!

All the years I've been working in aviation, from an apprentice all the way up to a B1 Licensed Aircraft Engineer it has always been messy when it came to try to eat well, find the time to look after myself. And then becoming a dad made that ten times harder as I also needed to prioritise whatever my family needed first. The stress, shifts, especially lots of nights, having to get a lot of work done (at work as well as at home) with little time to pay real attention to what I eat (and how much), it's been a slippery slope I could not seem to avoid sliding down.
Until I came across these guys! Darren, Kris and Dan have been extremely focused on helping me get to a healthier lifestyle and weight. Barely a month in I'm already down by 5kg, to a weight I have not seen on the scales since Covid! All while getting the help, support, guidance and gaining the knowledge I need to move in the right direction with my health. Still at the very beginning of this journey, but it is already clear that they know very well what they need to do for each individual they help, and help they do! I cannot recommend them enough to any Engineer, Flight or Cabin Crew, Office based staff or those working on the ramp. I've been on the fence long enough about my wellbeing, I fully recommend others to take this same first step towards a happier future self! Looking forward to what the future holds with their support and coaching too!

I joined this group in April 2025, having noticed several friends within the Aviation Industry loosing weight and with a spring in their step!
A quick look on LinkedIn and Facebook and their secrets were revealed and soon made contact with Darren
Started off at 105kgs, now down to 91kgs and I am looking forward to getting to my target of 80kgs in the coming months.
This is despite living as an Expat in the ME, with numerous internation travel commitments and customer entertainment. Home is France which is a further temptation to stray off course, on my regular visits,
Darren and he’s team are great: constant communication with advice, praise and constructive boll**ings as necessary.
When on the road, its always great to meet up with other Aviation Slimmer’s and compare notes on our journeys so far.

I am extremely happy to have joined the program. So far Darren and Kris have been superb and very supportive. I started at 102kg six weeks ago. Pre diabetic, enlarged intestine and liver and a lot of visiral fat around my organs. I am now down to 88.6kg and feel super! My energy levels have gone up. I think more cleared and just love how I feel and look. I am fitting into clothes that when I started I could not fit into and get lots of comments about I look. I would highly recommend this program to anyone that wants to still enjoy life without a fad diet. I am really enjoying the food I prepare and weigh and have not touched any junk food since starting and neither do I want to. If you want your life back, then come join this team. It trains you for life and to change your habits for the better. Thank you to all the team at aviation fitness for the continued support and guidance.

I am extremely happy that I joined Darren’s Coaching. Before this, I had been trying a bunch of different programs that I would buy here and there, not really knowing which one to fully commit to because they all kind of said different things. Another problem with those programs was figuring out where to actually start.

A big issue I had in the past was that there was just so much information in them. It almost required me to become an expert before I could even figure out what my next step was going to be. Darren’s program is the complete opposite. From the very first weeks, it was so cut-and-dry, so step-by-step, really minimal, and very focused. He just guides you through exactly what you need to do next.

For example: here’s how to use this app, here’s how to count calories, here’s how many calories you should eat per day, here’s how to structure your meals, here’s how to get your grocery shopping list, and here’s how to make meal prep super easy so you’re not spending hours in the kitchen every day.

I found all of this super helpful because, like most people, I’m incredibly busy. I have two kids, a wife, and I run a business. I don’t have time to dive into the literature and try to become a sports scientist. Having somebody who has already gone through all that just guide me on what I need to do—and what I don’t need to do, which is even more important—has made the whole thing simple and straightforward.

It’s been absolutely amazing, and I’ve lost 14.75 kg in the last six months since being on the program.
