How Much Cardio Should I be Doing?

So, I’m going to start this off by defining cardio because a lot of people actually question if what they’re doing is considered cardio. And there is some science to it and I know not everyone likes science.. but I personally enjoy learning the science and research behind physiology because when you become educated on how the body works, you can again, make educated decisions about what is best for your body and your goals! So, hang in there as we get into some science so you can understand more than just ya know.. cardio is good for your heart and you're doing cardio if your heart rate is slightly elevated.


Basically, cardio is any form of exercise that increases the heart rate and is typically labeled aerobic. Now technically cardio and aerobic are two separate terms because cardio is a form of exercise that increases your heart rate.. aerobic simply means “in the presence of oxygen", meaning the work or exercise that your body is doing requires oxygen intake, transport, and utilization. So when you are doing a cardio workout, you are working aerobically. So, while they are technically different, they are basically synonymous right, because they occur simultaneously. You can’t have one without the other. If you’re heart rate is elevated because you’re doing cardio, it’s also aerobic because your body is utilizing oxygen for energy. So through this episode, just know that when I talk about cardio I’m also talking about aerobic exercises.



Now, Anaerobic means the opposite.. "in the absence of oxygen". So aerobic exercises, and we can use long distance running or jogging as an example, is a form of cardio which requires constant use of oxygen transport and utilization as well as a separate energy pathway than anaerobic or nonaerobic exercises (exercises like weight lifting, strength training, or short sprints) and aerobic exercise consistently challenges the heart and lungs. So let me stop there and get into a little more science.. just stick with me through this…


Your body has to receive energy during exercise, whether its aerobic or anaerobic.. and muscle cells have to use either ATP or adenosine triphosphate which is a for
