HeartHero SOLO

HeartHero SOLO reimagines cardio as a skill-based game powered by your heart rate. Instead of guessing how hard to work, you train inside personalized zones that score what actually matters: Recovery, Endurance, and Power (REP). Recovery rewards how quickly your heart rate comes down, Endurance tracks steady, sustainable efforts, and Power measures precise high-intensity intervals. Together, REP turns every workout into measurable progress—whether you’re building longevity, improving performance, or just trying to stay consistent. Play anytime, anywhere, on any cardio machine, at home or in the gym. With HeartHero SOLO, cardio finally has structure, purpose, and a score you can improve.
