Had my 1st done july 2025 which helped me loads with the data I received and was given a plan to work on and while i didn’t follow 100% of the time i really think made a difference. Now being tested March 2026 my numbers have gone up and data proves I’ve got fitter. I’d highly recommend ENP for vo2 testing definitely worth your money and time because he gives so much data and plan it works.Posted on Christian JonesTrustindex verifies that the original source of the review is Google.

He explained everything in an easy-to-understand way and made the whole VO₂ max and metabolic testing process comfortable and informative. Highly recommend!Posted on Billy WilsonTrustindex verifies that the original source of the review is Google. Recently got my VO₂ max tested by Oisin, and honestly, it’s one of the best things I’ve done in a long time. I’m currently training for a 100k ultra and an Ironman, and the level of insight and data I got back was genuinely mind blowing. It’s completely changed how I’m thinking about my training. Couldn’t recommend it more if you’re serious about improving performance. Plus, Oisin is a really nice bloke, made the whole experience even better.Posted on John RhodesTrustindex verifies that the original source of the review is Google.

Thank you Oisin. You are a star.Posted on Holly FTrustindex verifies that the original source of the review is Google. I had a metabolic testing session today with Oisin, and it was excellent! The test was super simple yet highly effective, giving me valuable insight into my metabolic health. It’s helped me better understand how my body uses macronutrients and what my calorie needs are. Thank you for a great session! I’m excited to see how my results improve now that I have access to this data!Posted on James TalbotTrustindex verifies that the original source of the review is Google. I recently completed metabolic and VO₂ testing with Oisin. Both tests gave me real insight into my aerobic zones, fuel usage, and how to structure my training more effectively. Instead of guessing my pace or relying on generic zone calculators, I now know exactly where my easy, tempo, and threshold efforts should be. Afterwards Oisin broke down everything for me and answered any questions I had. This process has given me much more confidence in my training and a clearer path to improving my endurance.Posted on David EarlsTrustindex verifies that the original source of the review is Google. Oisin's testing and feedback was excellent, the summary is exactly what I was looking for. It's targeted, understandable feedback, he cuts out all the noise and made my goals and target metrics straightforward. Highly recommend!Posted on Tracey ConnorsTrustindex verifies that the original source of the review is Google. I did a VO2 max test with Oisin to get a more precise measure of my training zones for my first marathon. He is incredibly knowledgeable, attentive, and genuinely cares about your training, nutrition, and overall balance. The results were explained clearly and in detail, with extra valuable insights on nutrition and how to improve performance to reach your goal. He helped me realise I’d been overtraining and that I was in a better place than I had thought. Now I can train smarter, recover better, and actually enjoy the process. Highly recommend!
