OSR Fitness Avis 52

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.

If you’ve found this page you’re on the right path! Signing up with Oscar and Sam is the best thing I’ve done for myself in a very long time. I’ve loved every minute, and there are so many benefits. My physical and mental health are vastly improved and as a woman going through menopause my energy levels have gone from struggling to climb the stairs to now running up them. OSR have given me the skills, support and knowledge to change my life. They are also amongst nicest people you will have the pleasure of working with!

I had an amazing experience with OSR, especially with Sam! Their custom made diet menus, shopping lists, and training plans made a huge difference in my journey. Over the course of the programme, I lost nearly 7kg in a sustainable way while learning a lot about food, nutrition, and making better choices.

What really stood out was the accountability and follow-ups—whether through calls or messages, Sam was always there to check in, offer support, and make adjustments when needed. Since I don’t enjoy cooking just for one or two people, their straightforward and personalized recipes were a game changer. We even tweaked them a few times based on my feedback, and Sam helped me reflect on weeks where things didn’t go perfectly (spoiler: it was usually me not cooking!).

If you’re looking for a tailored, flexible, and effective approach to nutrition and training, I highly recommend OSR!

The help and support I receive on a daily basis is absolutely incredible Sam and Oscar are amazing if you want to start your journey to weight loss and exercise these are the guys for you ready to help at any point in the day the support and encouragement I haven’t found anywhere else I would truly recommend them without a second thought

This is my second stint working with Sam as an online personal trainer. I came back to Sam after trying other online trainers because of Sam’s consistently positive and supportive attitude which helps me believe I can reach my target weight and fitness goals, despite the many demands of a busy job. His daily text messages keep me accountable while the weekly calls ensure I know what the goals for each week are. After three months working with Sam I’ve lost weight and have improved my strength and fitness. I’m looking forward to continue working with him to achieve my goals.

Finding Oscar and Sam has been a game changer. I had been procrastinating about making the necessary changes. In the past i always had great initial momentum that would just fizzle out. Not anymore. I love our check-ins. I am a retired chef and their meal plans/recipe books are excellent. I love the daily schedules and reminders, they are a huge help particularly to busy people. I have dropped down an entire dress size and built muscle strength in our short time together. Thank you so much!!!
