I'd previously written off fat burning as a thing, but he swears by it, and certainly lives the part. Any thoughts?
I’ve gone down that rabbit hole as well- less for fat burning, more for aerobic development- but the same method.
Two things I have identified about it for me:
1. It absolutely does work in terms of aerobic development if you stick to it, but it takes a lot longer than I thought.
2. Keeping below 130 is almost impossible in the summer, especially if the dew point starts to rise. I have abandoned any hard and fast number/“zone” and just focus on conversational pace (exactly what it sounds like).
I’m not some super speedster- I was once fairly fast for a hobby jogger (17min 5k, so not great but decent). As I get older and train more like this, I’m not quite that fast anymore but I feel like I can go forever.
75-85% of runs in the low zone, the rest are pretty close to max effort. Easy days easy, hard days hard. This is a vast oversimplification but it seems to work for me.
If I was 100% focused on fat burning, I would do long, fasted state low heart rate runs/rides. Like 90mins+.
