I am 65 this year and consider myself relatively fit but really wanted to get a baseline of where I am re my age. Dan was so encouraging and positive, although I don’t run he encouraged a fast pace walking in the thread mill. Delighted I did it.
Really enjoyed the experience and found it super interesting! Dan and his team were great at putting me at ease before we stayed and took the time at the end to run through my results and explain how I can improve on them. Highly recommend Ageless VO2!
Really good. Interesting to see results, would like to repeat to get a comparison in time
Booked for VO2 Max and attended Ageless Vo2 in March 2026. Handy location. Very clean and good facilities. Daniel took time to prep me for the test and walked me through the results afterwards. I will definitely be back for a further assessment in a few months to check my progress towards longevity. Thanks Ronan, Dublin (Age 55)
Everything thoroughly explained and everyone very friendly and professional. Very informative and scientific approach to your training.
Ageless VO2 was an excellent experience from start to finish. The process was smooth, professional, and genuinely valuable. Daniel was superb throughout. The insights I took away have already helped me sharpen my training and understand exactly where I can improve. Highly recommend for Hyrox athletes aiming to improve running and recovery after stations.
I visited Ageless a few weeks ago. Really enjoyed the experience. The results and the advice Dan gave were really insightful. Highlighted where my fitness level was, and best steps to make improvements. Working away on that and look forward to follow-up to gauge my improvements
I had an amazing experience with Daniel at Ageless Vo2 testing. From the moment I arrived, he made me feel completely at ease and explained everything clearly and professionally. The VO₂ max test itself was challenging but incredibly well-run, and Daniel’s encouragement and knowledge made a huge difference throughout. I learned so much about my fitness, performance, and how my body actually works, which was fascinating and motivating. It wasn’t just a test, it was a real learning experience. I left feeling empowered, informed, and excited to apply what I’d learned. I can’t recommend Daniel and Ageless Vo2 highly enough.
