FXI

"The best thing is, my 5k times have been improving beyond anything I had expected, I run a timed 'Parkrun' 5k every Saturday morning and I have PB'd EVERY SINGLE WEEK since I started in conjunction with the FXI in early September. For me, this is tremendous and all done with very little running training in between, I suspect it might be the FXI!" -Mike

"Sarah has lost about half a stone and has improved her wattage output from 294, to now being consistently in the 400's with a high of 475. Sarah has also consistently PB'd in the weekly 5km time trial parkrun, and she also has more energy and is feeling fitter."

"Upon initially hearing about the study from my friend Mike I was overwhelmed with excitement at the possibility of playing a tiny albeit very important part in this study which could ultimately lead to greater understanding and as yet unknown and boundless benefits to health & fitness.

"Although I am only part way through my 12 week period of FXI regime / training, I can say without any shadow of a doubt that this method of training whilst been very difficult and extremely demanding has indeed delivered large and notable improvements to my overall fitness. An example of this can be easily seen by improved fitness whilst riding my road bike in my daily 20 mile return commute to work which has become much easier and pain free as well as during my regular jogs in the park where I feel I can go faster and feel the same benefit without running for ages in the same style as the FXI.

"I am very committed to the FXI work and what it stands for and what it could achieve, as a result have adhered to the spirit of the exercise study and give it all I have got and always give everything in the same intensity as original initiation day at the university. I have been feeling great and am grateful for the opportunity in this ground breaking study." -Henry
