    I've only counted my heart rate a couple of times and I managed to get into decent shape. I truly doubt it matters all that much - lift heavy, sprint, take some nice walks, play around. That's the good life and doesn't require a heart rate monitor.
    If you are new to the PB - please ignore ALL of this stuff, until you've read the book, or at least http://www.marksdailyapple.com/primal-blueprint-101/ and this (personal fave): http://www.archevore.com/get-started/

    I don't think you can do all that much harm to yourself in 20 minutes, unless you spend it shooting heroin or something.
    IMO 20 minutes at a higher heart rate would be fine, especially as you say you enjoy it.

    The way I understand it is that the 75% HR will allow you to maintain your current endurance and get the benefits of frequent exercise without falling into "chronic cardio".

    Sprinting/interval training (walk-sprint-walk...) allow you to push your cardiovascular system in a way that doesn't result in chronic cardio.

    How fast you're going at 75% HR should increase over time as a result of the sprinting and interval training.

    Heart rate obviously!
    Fits in the context of talking about the 75% (of maximum heart rate)

    Train under your aerobic threshold - around 180 minus age. This will be easy, but effective.
