Actually this is not true. Again, you’re full of **** Epic Days. I know you blocked me lol but I’m saying thing so that others can see through your garbage.This is real cardio training done by professionals and those who are in the know.
Marathon training is for PROFESSIONALS is not this at all. They hover at around 90% of their max heart rate in the marathons and in the training too. All endurance athletes will tell you. You yourself are not an endurance athlete. I used to be.
Pro endurance athletes are able to hold their heart rate at around 90% almost indefinitely, it’s just painful to do so. And when they get ready for a meet/competition? They can get closer to around 95-98% of their max heart rate. That’s why they’re always so extremely out of breath when they finish their race. It’s also why thee still out of breath 5, or even 10 minutes after their race is already finished. This is also why some research says that marathon training is detrimental to your health. You have no real sports or athletics training, most of what you did was done in the military, and let me tell you, my high school coaches made us do **** that Navy Seals don’t even do. I remember watching a documentary on the physical training those guys did, and I remember thinking “huh, we do that stuff all the time during practice, that’s just a standard day...” and the narrator was saying how what we the viewers were watching was a harder-than-usual day lol.
Your body always uses glucose. It’s just that eventually it’ll need to use carbs MORE since they’re broken down more quickly. Training harder WILL make your heart adapt faster and get better at cardio FASTER than training lighter. This is fact. Our body responds to stronger stimuli with a greater adaptation than a weaker/lighter one. This is fact. Your heart is the main thing in your cardiovascular system. It can use glucose, fatty acids, triglycerides, pyruvate, amino acids, and lactic acid for fuel when it needs to. It only does so once you get to a higher heart rate, but it still DOES use all of these at the same time. Your skeletal muscles isolate the fuel source more, not your heart. But even then, they can still mutiple sources at a time.Remember, exercising (running) at your cardio threshold actually burns fat for fuel. That’s how you body was designed. If you go over your threshold you start cutting into glucose and start cutting out burning fat.
