Aerobic Health and Mitochondrial Function

January 24, 2025

The one thing is I will front load the cardio for almost every client. And the reason I do is based on the metrics. It has nothing to do with fat loss for most people now for really overweight people, yeah, I'll front load it because of that, because of the caloric output and to get their mitochondria beefed up quickly so they can oxidize quickly Same way explain that part because I think this is like if people could understand that when you have really good aerobic health and you are generally aerobically fit you burn fat better, you burn carbs better, you find it easy to lose weight, you find it easy to stay lean because you have the cardio there. And it's, this is why I hate social media, but like saying, bashing on cardio as well in different ways. It's like, no, seriously, prioritize your cardio because it will make fat loss so much easier for you please save my pain and now the problem nowadays though is we were the pendulum swinging and in our industry the pendulum swings one side or the other it never meets in the middle so it's like it used to be no cardio you don't need cardio now it's like oh cardio is healthy so we need all the cardio wait wait wait no no don't go over there like you were over here the point isn't to go over here it's to stop right here. It's again, like I need a little bit of cardio, not all the cardio. So it's like, especially if you aren't in building strength and strength and size, which again, should be, should be a cornerstone of your programming. But if we look at, we need to, we need to define what cardio is, a cardiovascular respiratory training. It should primarily be used for adaptations to the cardiovascular respiratory system, meaning the ability to get oxygen in the body, pump through the body, and then carbon dioxide pumped back to the heart to then be released into the atmosphere. So if you're going to put in cardio in those initial stages, use it because you're trying to get in better aerobic cardiovascular shape. Use it because it is the best, easiest tool to get your mitochondria oxidizing the fuel that you're trying to get off your body. Because when you release fat, it has to go somewhere. So it goes into your bloodstream and it has a choice. It goes around the body and it tries to find a cell to go into so that it can be either oxidized using oxygen to create energy, or we can use it to create heat. Now, if it can't go into the muscle and it can't go into the mitochondria because you don't have good mitochondrial volume or your mitochondria is not working in like peak tip top shape. It's going to sit around in the bloodstream and it's either going to sit there or it's going to go back in the fat stores. So you have on one side, you have the release of fat and you have the transport of fat. On the other side, you have the actual getting rid of the fat by turning it into either carbon dioxide and using it to create energy or using it to create heat.
