Had very good experience with Daniel and was very informative with the results after the Vo2 max test. Received email with all information and recommendations et. Highly recommend Ageless Vo2 Thanks Daniel
I was treated very professionally and everything was explained prior to each step in the process. Dan explained the results and the way forward using data that was very interesting , informative and easy to follow. Getting the full results by email really was great and the suggestions and advice were great.
As an average female in my 50’s I wanted to gauge where I was at for long term health. I was happy with results and was given clear manageable guidance on how to improve. Overall a very positive experience.
I did my VO2 max test with Dan. The whole experience was excellent. Dan know his stuff and went through all the results straight away and followed up with an email. I’m booked back in 3 months to test again.
Really enjoyed the test! Daniel so friendly and breaks down exactly what needs to be improved based on your results from the test.
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)
