As the creator of @zonescardio, you’d think I’ve always been a runner or at least a cardio person.

Not even close.

I’m an exercise physiologist and researcher who has analyzed heart rate data from 30,000+ runners, but for most of my life, I never enjoyed running or cardio workouts myself.

That changed two months ago when I started consistently using the @zonescardio app.

Now I’m hooked. The workouts and schedule have become part of my daily routine; I feel better than I have in years, and I’m even recovering faster from my strength workouts.
