Nobody has done a good job of explaining it to me, so my concept of exercising to lose weight may be incorrect. I picture burning fat and losing weight as a tipping point. My understanding is that fat burn begins after 30 minutes of a cardio workout. So, all the calories burned before 30 minutes in the cardio workout aren’t fat calories (maybe they’re carbohydrate calories?).
So the purpose of the work-out is to continue to work after that 30 minute period. For the first 30 minutes of every workout, I am not accomplishing anything aside from getting to minute 31. The longer I can go after the initial 30 minute period pays dividends because if I quit at minute 40 I’m only getting 10 minutes of fat burn. So instead of stopping at 40 minutes because I’m tired I might as well go to 50 minutes because if I don’t I’ll have to work for 40 more minutes tomorrow to gain what I would have in 10 more minutes today. Does that make sense? I’m sure it does. But I’m also sure that my ideas are skewed or they aren’t based in facts. Can anyone tell me if my understanding is incorrect? -unfigurable
