Ask them to explain why they think their body will start burning muscle once they get over 130bpm, I bet they won't be able to give you any kind of scientific explanation, just a "well this guy told me" response.
It's not about your heart rate, it's about the resources your body has available. Food in the stomach, glycogen stores, fat, muscle it can all be used to fuel your body. As I stated above; muscle is a last resort. If you want proof it has nothing to do with heart rate, go look at somebody suffering from anorexia.
actually i am gonna ask a few of them where they got this info
but it is seems to be wide spread
"well this guy told me"
i dont think thats the answer, all these guys do and research and talk about is
lifting weights,food and getting stronger lol
so they can give a lecture on any of those topics
