That’s what I figured. But I’m still a little confused about the relationship between HR, AeT, ME, and general performance.
From my readings, I have the impression that each weakness has a unique solution: ie. more aerobic base building if you’re breathing too hard uphill or more/better ME if your legs feel heavy. But my understanding of HR is that it’s a measure of efficiency of how much blood your heart can pump for a given exertion (hence why HR rises when going uphill even at the same pace). If I were able to reduce the level of exertion required through more strength and ME training (to an extent/piano movers analogy in TFTNA), then wouldn’t that also reduce the HR required to maintain a certain pace while going uphill? Or am I wrong to think that aerobic capacity and ME are coupled in that way?
