Should You Do Cardio Before Or After A Workout To Burn More Fat?
Показать описание
So while I was finishing up some cardio, I figured I'd give you guys a quick chat on how you should be timing your cardio. Should you be doing your cardio post-workout or pre-workout?
Well, in order to understand what you should or shouldn't do, you have to have a quick understanding of aerobic and anaerobic activity.
0:23 Aerobic activity is a low-intensity workout while anaerobic activity is a high-intensity workout.
Aerobic activity creates a lot of energy, and anaerobic activity needs more carbs to create the same amount of energy. It's a faster process, but it burns through carbs really fast. So essentially what I'm saying is, when you're doing your cardio, you're utilizing fat as a source of fuel and very little glucose, and when you're doing weight training or any kind of High Intensity Interval Training, you're utilizing carbs as a source of energy, and a lot less fat.
1:17 Cardio utilizes fat as a source of fuel and weight training utilizes carbohydrates.
So should you do cardio after weight training?
When weight training, you're utilizing carbs as a source of fuel. When you're doing post-workout cardio, you're using fat as a source of fuel. You don't necessarily have to dig through the carbs to get to the fat...it's a little bit of a different system.
However, I am still a fan of doing your cardio post-workout, and I'll give you some reasons why.
2:08 Mechanistic target of rapamycin (mTOR) integrates the input from upstream pathways such as insulin and amino acids.
mTOR is what is responsible for building muscle. But there's another enzyme that we have to pay attention to...
2:34 5'-adenosine monophosphate protein kinase (AMPK) is an enzyme that plays a role in cellular energy homeostasis, and studies have shown that aerobic activities increase AMPK, which decreases mTOR.
So resistance training becomes a lot less effective by having cardio done before-hand.
So this simply means, if you put your cardio at the end of your workout, you won't have to deal with those power reductions or mTOR signaling issues.
I'll See You Next Time,
