Enhance Your Performance, Health, and Experience While Running with the Counterpace Guidance System Exciting new insights into the mechanisms that deliver oxygen during rhythmic physical activity are the basis of the Counterpace training platform - a novel sensor-based system designed to guide you into your zone of optimal efficiency every time you run. Counterpace guidance prompts you to synchronize each step of your run with the relaxation phase of your heart, offering several powerful physiological advantages. Studies of counterpulsation during running suggest this this simple technique has the potential to allow you to run longer and faster with less effort, potentially also improving health benefits, cardiac safety, and recovery time.
