Five years ago, Tyron Groenewald was overweight, stressed out, and sick. After his cardiologist diagnosed him with left ventricular hypertrophy — a condition where the ventricles have to work harder to pump blood, resulting in an enlarged heart muscle — Groenewald decided to make some major lifestyle changes to prioritize his health.

His hard work has paid off. Just half a decade later, 35-year-old Groenewald is down 114 pounds, he runs every day, and his left ventricle now measures within a normal range. Along with implementing a healthier diet and more physical activity, Groenewald says measuring his heart rate variability daily — he’s currently on a 1100+ day streak of using his Elite HRV monitor — has been a key part of his health journey.
