OSR Fitness レビュー 

When I turned 40, I slowly started to feel like I was falling apart and physically everything was starting to feel harder than before. I felt stiff and tired all the time and I had put on weight without doing anything different. I started looking for an exercise programme to help me feel fitter but I wanted someone to just tell me what to do so I didn't have to think about yet another thing on top of my to do list. I also wanted to take out the guess work as I really didn't know what I was doing. I wasn't specifically also looking for a nutrition programme but didn't realise at the time that I really did need that too. Sam answered a comment I made on one of their videos and what happened next really impressed me. We had two very long conversations about my background, my current situation and what I wanted to achieve. I decided from those conversations to sign up and just see. It's been the best decision I've made for myself in a very long time. Sam and Oscar have genuinely changed my life. In just 3 months, I am a new person. The most unexpected change has been with my mental wellbeing. I'm calmer, I'm a better and happier parent and seem able to handle stress in a way I never could before. I feel less stressed out day to day and I feel like I've taken control of my body again. Physically, I'm no longer stiff everywhere. I feel stronger, I've lost 5.5 kgs already and I'm down a dress size. I look at myself in the mirror and feel better about what im seeing. I can now see the start of some definition in my arms and I love it! I'm starting to loose my back rolls, my skin feels softer ... Oscar gave me things to do to try to improve my sleep and after years of bad sleep I am now sleeping again! My last period had zero PMS systems..the positives just go on!

The weekly check-ins with Oscar really does centre and focus me and keeps me on track and they are always at the end of a WhatsApp so I'm not left in the wilderness alone!

Best of all, I've not really found it difficult to make these changes even whilst having a young family and working part-time. They make it achievable and don't expect perfection which is realistic. They send videos from time to time with helpful tips or things to think about. The app is brilliant. These guys are truly lovely people and really know what they're talking about. They've created a programme that really works and run it really well. I can truly say that whatever happens from now I can't ever go back to the person I was 3 months ago because I'm creating new achievable habits that make me feel good. Initially I set a target for weight loss but it's now so much more than just loosing weight and reducing stiffness, it a change of routine and mindset where I'm also making my needs and health a priory after so long. 100% would recommend!

Working with Oscar and Sam has completely transformed my approach to health and fitness. What I live about their coaching is how seamless the plan is...it fits perfectly around a busy week, the workouts are manageable, and the family can eat the exact same meals without feeling restricted. I’m eating healthily, seeing incredible results and I’m genuinely never hungry.
​The plan is completely tailored to me without being odifficult to follow. Everything is rooted in simplicity and practical advice aimed at achieving my personal goals. Whenever I have a question, need something tweaking, or require a bit of inspiration, Oscar and Sam are right there to support. They don't just tell me what to do they help me understand the process so I can take control of my own journey. All I have to do is show up and follow the plan. This has been an investment in my future, and it's worth every penny.

Having had my son a couple of years ago, I was stuck in a vicious cycle of lack of energy and time to exercise and fuelling myself on high calorie, low nutrition food to keep myself going. I finally reached a low point and realised enough was enough. I started investing in myself and not only did I lose weight, tone up and my energy sky rocketed but I started making more positive decisions for myself in my wider life. I started to have confidence in myself again. This plan is easy to follow, easy to fit into life and allows you to eat food in a balanced way so that you’re not screaming for snacks! It has given me a new relationship with how I eat and shown me I don’t have to spend hours in the gym to really make a difference. Thanks for everything guys!

I really enjoyed the four-month coaching programme with Oscar and Sam.
The one-to-one online coaching was far more effective than any random workouts found online.
I really enjoyed our weekly coaching calls. It was a great opportunity to ask lots of burning questions and keep me on track.
The coaches were always available on WhatsApp whenever I needed support or, again, ask more questions! Their advice on nutrition and training was practical, easy to follow, and tailored to my health, fitness goals and budget.
I especially appreciated how they kept my nutrition simple and sustainable long term rather than overcomplicating the process with endless list of suggested supplements.
I've learnt a lot and achieved great progress. I'm looking forward to continuing to work with them, getting stronger, fitter, and more chiselled!

I'd highly recommend OSR Fitness to anyone looking for knowledgeable, supportive coaches whether you are an experienced gym goer or just starting.

Oscar and Sam are incredibly professional, knowledgeable, and reliable. Thanks to them, I haven't just lost weight—I’m also significantly fitter and stronger. They tailor both the diets and workouts to your specific goals, and they are always available to answer questions or offer support. I highly recommend them!

Oscar and team really do make working out fun and exciting. I look forward to it every time.

As a Private Chef, eating patterns and habits are hard to manage, even if you know everything there is to know about food.

I scoured the gram for a non AI fitness programme for about 2 years and came across Oscar and Sam. Motivating reels, British, full of confidence and energy and true believers in their programme and being able to make a difference to chaotic lives.

I started in May 2025 at the start of the Weight loss jab hype. Totally against this I wanted to find a way to understand my eating habits against the amount of exercise I was taking and not losing weight.
It turns out I was overworking and not eating the right things or amounts at the right time.

This is a complete 180 just mentally and then a complete 360 which takes a long time.

Oscar has tirelessly guided me on my journey. Available, present and encouraging. I am feeling good, eating better , working out less, varying my workouts more and now am determined to nail the sleeping patterns. Slow wins the race believe me!!

Oscar has made this journey achievable with a program designed specifically to my needs and constraints. I am soon to be 48, have a busy job that involves a lot of travel along with being a dad of 3 young children. I started the program 4 months ago at 204lbs and today am coming in at 185lbs and look and feel completely different. I was already working out 3 or 4 times a week and I still play football but I wasn’t seeing any results and was arguably going backwards. Oscar put together a program based around the time I have (not a lot) and the equipment I already owned. The diet also took into account our family evening meals we all have together. I’ve loved the regular check-ins which have helped to hold me to account and the regular tweaks to the program have ensured it hasn’t gotten monotonous. I’ve actually struggled at times to eat the amount of food needed which surprised me, I assumed I was doing to be hungry but that hasn’t been the case. People I haven’t seen for a while mention how good I now look and I am really looking forward to seeing what the next 4 months brings. My before and after pictures are already looking really good and I’ve got a spring in my step again, plus it’s helped with my football performance on a Saturday, I can manage 90 minutes now without requiring 3 days of recovery!

I have known Oscar and Sam since the bootcamp days back in 2018/2019 but after peaks and troughs in my fitness goals I decided to take action. Having done online fitness coaching in the past I was a bit hesitant but Oscar and Sam's method surpassed what I previously had experienced. A blend of positive psychology, mindset and somatic work has helped me immensely improve my outlook and view on nutrition, my body and approach to strength training. I have got stronger, lost inches and feel better in myself as a result. Oscar has also given me the continued encouragement, support and belief that change is possible especially during those dips! I can highly recommend working with Oscar and Sam as they certainly know their stuff, will motivate and be there for accountability! Thanks for all the support and encouragement, this is just the beginning as I continue my fitness and health journey!

Oscar & Sam exude professionalism.

Their advice is second to none.

Their knowledge knows no bounds.

Because of their unwavering expertise, I have lost a huge amount of weight, become fitter and gained muscle!

Signing up with OSR has been a win/win 100% no brainer.

Being healthier is really fun 😎

I was skeptical about having remote trainers, but after having been with OSR for almost 2 years now, it just works!
Sam and Oscar have been amazing to work with, they are available for any questions or workout tweaks and with their check-ins and messages, I’ve never feel like I’ve been abandoned!
Then there’s the result, I’ve gained over 20 lbs of muscle and am in the best shape of my life.
Highly recommend these guys!

Working with OSR has been one of the best decisions I've made in a long time! I never could have imagined finding a trainer that works so well with my life, my style, and my needs. I love the mindset shifts I've experienced around food and the workouts, tailored to me and my needs, are spot on and effective. Oscar has been flexible when needed, direct when needed, and supportive and encouraging always! It feels amazing to be as consistent as this collaboration has made me and I am grateful knowing I have the knowledge and support whenever I need it. Watching and feeling my body change and become stronger is amazing, feeling more like myself and confident about what's possible is exactly what I wanted and what I am getting. I am nothing but optimistic about the months ahead and the continued success working with OSR will help me accomplish.

As a mama to twins my time feels almost non existent but making my recovery a priority with Oscar has been one of the best decisions I have made. Training with him has become an important part of my week. He supports me with my health and eating habits while giving me a plan that makes sense and still challenges me. It feels amazing to be cared for when so much of my energy usually goes into caring for others. The bonus is I am getting stronger every week. I would highly recommend working with OSR Fitness!!

I found Oscar and Sam in the middle of my year long treatment for stage 3 gastric cancer. I was looking for support and guidance to help me gain strength and weight, the opposite of what most programs talk about. Oscar and Sam, although across the pond, had the knowledge to guide me with how to eat and how to work out to reach my goals. My unique situation didn’t throw them off and I am so grateful I found them. I have been working with them since about half way through my treatment and I’m now just about 2.5 months post treatment and already feeling stronger than ever . Muscles are showing and I’m learning to eat more protein and calories in a way that works for my new body with their support. Oscar is my 1-1 and knowing I can reach him with any questions about my health and strength is so important after going through a year of cancer treatment.

Oscar and Sam are amazing. I wish I'd found them sooner in my journey. They have helped me loose what I couldn't on my own but also have a much healthier relationship with food. I have built muscle I never knew I had and managed to stick to the plan 99% of the time. Iv got to my goal but love the process and the guys so much iv decided to stick it out even longer as have seen so many additional benifits beyond the scale wins.

I trained with Only Serious Results (OSR Fitness) and had a great experience. They focused on lifestyle change and fat loss and provided structured, professional support throughout. The coaching was personalized, encouraging, and grounded in science. I appreciated how they explained the “why” behind everything, helping me build sustainable habits instead of quick fixes. They genuinely cared about my progress and were always available for questions or adjustments.

If you’re looking for accountability, structure, and real results without gimmicks, I’d definitely recommend OSR.

Oscar and Sam really care about us. I was impressed that we had face to face zoom every week- they really listened lmao how you like or dislike the meal plan, Oscar would tweak things for me to make sure I liked what I ate, that the exercises were not too m7ch for me but still challenged me. So personalized. That open communication and encouragement, the app with reminders and workouts- it all gave me the tools and motivation to succeed and push forward. I lost 6 lbs (I didn't have much to lose to begin with), am fitting back in my clothes and FEEL pretty. This isn't the end, it's the Beginning. Thank you Oscar!!

Truly an incredible experience working with Oscar and Sam. Their program taught me so much about how to exercise and what to eat to lose weight and feel
strong and healthy. I was very overweight and inactive and confused about what to eat. I had tried all the fad diets and rando workout plans but nothing moved the needle until I joined OSR. I have lost almost 50lbs and am so strong. I had never lifted weights before and now I love lifting and making gains at the gym. I am supported and inspired to move and drink water every day. The 1:1 coaching and personalized plan is remarkable. I can eat the foods I like (picky eater over here!) in a way that supports my health and wellness. Oscar is my sounding board for everything health and wellness including my mental health and I really appreciate the support. The program is all in but not hard. You just need to learn what works for you and these guys are with you every step of the way. Hate smoothies and running - they won’t make you eat them or run and you can still be successful! Who knew? Recommend wholeheartedly to anyone that is serious about improving their health and wellness and doing so in a way that teaches you what to do. Love love love my time with OSR!!!!!

What a great experience working with OSR has been …the best decision I made to work with them and I have benefited so much . My mindset and the knowledge and guidance I gained has not only helped me get fitter slimmer and definitely focused on a much healthier path. I cannot recommend Oscar and Sam enough …for me it’s been a definite success .

stumbled across an OSR post on Instagram that eventually lead to me signing up. I was a bit skeptical, out of my comfort level and not really sure what to expect. Sam and Oscar have been amazing throughout the entire process. They are supportive, motivational and informative. My goal was to lose weight but I gained much more. Joining OSR has changed my mindset, my drive and it has helped me through some hard times. The motivational videos, the text messages, the weekly check ins, the personalized menu plans, the workout schedule but most of all, all the support thst Sam and Oscar offer is what makes this program different from the rest. I highly recommend joining OSR to anyone who is ready for a change, a healthy reset or just someone who wants to feel better.
