WHAT PEOPLE ARE SAYING ABOUT THE FRONTIER X
Tim Hutchings
Marathon broadcaster and 1984 UK Olympian
" What’s groundbreaking about the Frontier X is that this information has never been obtainable outside a lab. It could potentially have given me a warning about my building atrial fibrillation, a heart defect that can randomly develop in any one of us. "
Paula Radcliffe
Former Women's Marathon World Record Holder
" The heart and lungs are the fundamental foundations of all endurance sport. Frontier X enables us to protect and listen to them, thus helping us all to work with our bodies in far greater harmony. "
Michael Conlon
Founder of Finish Line Physical Therapy
" For endurance athletes, Frontier X is a game-changer that impacts optimal training load and performance by measuring breathing rate. For anyone who exercises, the additional measurement of overall heart health is a potential life changer. "
Yash Muthiyan
Running Blogger and Regular Marathoner
" Heart rate tells only a small part of the story. Real effort depends on breathing rate and cardiac strain. Frontier X gives me a detailed ECG for every run and helps me keep track of my training load based on real effort. "
Ross McGraw
Team USA Triathlete
" When I was first introduced to Frontier X I dove into what data it could provide, the metrics and the technology. What I did not anticipate was that using Frontier X would actually make me a better and more mindful athlete. "
Paul M.
Frontier X User
" The Frontier X is for anybody who wants to understand how hard they are pushing themselves during training, in a way that is more meaningful than just measuring heart rate."
