I did cardio wrong most of my life.
I thought being puffed and exhausted was the goal. The thought of an “easy run” seemed like a waste of time. It led to a poor relationship with cardio, one that I’m still trying to unlearn.
What I learned in the last few years is that the vast majority of cardio training should be at low levels of intensity. This is in your Zone 2, or 60-70% of max heart rate. At this level, you should still be able to keep a conversation, but it’s ample time spent in this zone that really builds your aerobic base.
Conversational cardio, it’s a great benchmark to get your cardio right.
