STRENGTHEN & PROTECT YOUR HEART
ANYTIME, ANYWHERE.

The world’s first and only consumer product that provides real-time continuous feedback on your heart health - wherever you may be.

Chest worn device used for athletic training, cardiac rehabilitation and remote monitoring - keeping you healthy and away from hospital.*

“The device measures cardiac strain, a sign that you are pushing so hard that the heart muscle is not getting enough oxygen.”

“By listening to your heart and lungs, this strap measures real-time cardiac strain and breathing rate for a more accurate reading of effort.”

“The device measures cardiac strain, a sign that you are pushing so hard that the heart muscle is not getting enough oxygen.”

“Rather than just beats per minute, the chest-mounted computer measures and records the functioning of the heart and lungs."

“You’ve heard of smart gadgets that can actually track our fitness, but the Frontier X really takes it to a whole new level.”

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. "

Dr.Anju Helen Jain

Frontier X User

" Using the Frontier X makes me stay in that area in which I am exercising enough to strain the heart muscle, therefore train it, but not so much that I precipitate a cardiac event."

Budd Coates

4-time Olympic Marathon Trials qualifier

" Frontier X offers real-time feedback on breathing, paired with stride cadence allowing the athlete to hone in on the perfect pace for the distance being raced or the workout being run. "

Jonathan Cane

New York City endurance sports coach

" Frontier X is the first product to provide the ability to monitor breathing rate and thus gauge intensity using practical and scientifically justified methodology. "

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."
