" 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."

" 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. "

" 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. "

" 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. "
