Add 5 if you’re in shape.

This is from Training for the Uphill Athlete.

Method is from Dr Phil Maffatone who is the godfather of Zone 2 training.

I've heard 220-age but have never multiplied by .66. That results in absurdly low rates.

220 - age = Max HR. This is upper limit of Zone 5 training. Fat burn is Zone 2.
