Is It Better To Do Cardio Before Or After Resistance Training?

By Howe Russ


Today's question is one of the most popular among those who are trying to learn how to lose weight, should you perform cardio before or after weights? Today you'll discover the factual answer to this often debated topic.

For many years, this was a subject which was usually answered with personal opinion. There was no real proof whether it was more effective to perform cardiovascular activity before or after a workout, so most people would simply do what worked for their own body and pass on their findings to others.

Recent studies showed beyond any doubt that performing a cardiovascular workout before resistance training was far more effective than doing it the other way around. Today we'll be delving into two of the most well documented studies in this area, showing you why they reached their controversial conclusions. [

That's not to say you can't get results the other way too, obviously. But recent studies at the James Maddison University found that case studies doing their resistance workout first were unable to keep up with case studies who were getting through their aerobic exercise first. When it came to building lean muscle, the 'weights first' group found that their progress was substantially blunted in comparison.

For those who are training for fat loss, the findings were also highly in favor of doing aerobic exercise prior to any barbell work. The Journal Of Strength And Conditioning discovered that weight loss, specifically fat loss, was increased greatly in individuals who did their aerobic exercise first.

Those facts may be controversial to many fitness enthusiasts, who opt to perform their resistance training first. The theory behind that method is that they don't want their muscles to be tired by aerobic exercise when they begin pushing out repetitions. This makes sense and it's an approach which does yield results. However, science suggests that switching them around is far superior for both fat loss and lean muscle development.

There are two key enzymes which play important roles here:

* Adenosine Monophosphate-Activated Protein Kinase (also called AMPK for short!)

* Mammalian Target Of Rapamycin (also called mTOR for short!)

You may have heard these two enzymes discussed in fitness magazines and bodybuilding gyms in the past. If you are performing aerobic activity the body increases the release of the AMPK enzyme to help your muscles adjust to endurance activity, while signals the beginning of the muscle recovery process at the end of a workout. For about an hour after you hit the weights, you'll have a surge of mTOR in your body and this is perfect for consuming post-workout nutrition. After six hours, the spike in mTOR wears off and your body returns to normal. []

By spending that crucial hour still working hard in the gym on a bike or treadmill you do two bad things. Firstly, you waste that golden hour of mTOR release. Secondly, you'll release more AMPK which actually blunts the release of mTOR, too.

So, should you do cardio before or after weights? Whether you want to learn how to lose weight or how to pack on lean muscle, recent science is heavily on the side of performing your aerobic activity before you pick up a dumbbell.
