Why Performing Cardio Before Weights Is Better For Building Lean Muscle

By Howe Russ


Should you do cardio before or after weights when you're trying to build a leaner physique? If you're trying to learn the basic principles of how to lose weight, today we will answer this popular question for you.

There are numerous areas in the fitness industry which, until recently, were shrouded in mystery. This is one of them. Despite the fact everybody knows someone who has some fitness knowledge, until very recently the answer to this question was based entirely on personal opinion because there weren't sufficient studies to give a definitive answer.

That's no longer the case. Today we'll be looking at a few recent studies and talking about why science has now shown cardiovascular activity to be more effective when performed before resistance exercises, as opposed to afterwards. []

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.

Furthermore, the Journal of Strength and Conditioning recently carried out a study on this topic to discover the fat loss benefits, too. Their findings were similar. Those who performed aerobic exercise before hitting the iron were able to increase fat loss results considerably over the group of case studies doing it the opposite way around.

Of course, it is highly important to remember that if you are regularly training with weights and getting a good deal of cardiovascular activity into your life then you will still see positive results no matter which order you perform them in....

There are two key enzymes which play important roles here:

* AMPK (aka adenosine monophosphate-activated protein kinase)

* mTOR

You may have heard of these before. AMPK is the enzyme responsible for helping the body adapt to endurance exercise, while mTOR is considered an 'on' switch in the muscle building process. After you finish a weights workout, your mTOR levels surge for around one hour. This means consuming quality nutrition at this point will ensure quality lean muscle gains. After around six hours, levels of mTOR return to normal. []

If you finish your weight training and then sit on a bike for 45 minutes you have not only wasted the bulk of your golden nutrition window, you have also made a fatal mistake. When the body releases AMPK, i.e. during cardiovascular exercise, this hormone doesn't co-exist with mTOR and actually kills it off.

Although you can certainly achieve a fitter physique regardless of whether you do cardio before or after weights, recent studies seem to weight heavily in favor of performing your aerobic activity before you begin using dumbbells and barbells. In order to learn how to lose weight, getting past common myths like this is part of the battle. You've just done that today and can now apply this new knowledge to your own training.
