Same walk, lower heart rate—that’s how you know it’s working. Track your progress over weeks and months.
Cardio is boring.
That’s the point.
Most fitness apps fight boredom with badges, streaks, and confetti. Boring Cardio leans into it. Set your treadmill. Walk. Come back tomorrow. The reward isn’t a notification—it’s your heart rate dropping five beats per minute at the same settings you did last month.
