Redline Cardio believes that better cardio starts with your heartbeat. That's why we've studied more than 35,000 exerciser's to develop a heart-rate specific and progressive training program. Redline cardio is a cardio training app that creates customized 20-minute cardio workouts based on what your heart is doing while you exercise. We use this approach instead of using age-predicted numbers that assume we're all the same based upon the date we were born.

Redline Cardio provides a schedule that helps you commit. 20-minute workouts that negate the issue with traditional cardio workouts and noticeable results quickly. Programs for weight loss, wellness, performance, and tactical.
