Why Performing Cardio Before Weights Is Better For Building Lean Muscle

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.

Only in recent years has science shed any light on this topic. Until as recently as five years ago, the entire answer to this question was based on theory. This led to people being told different information by everybody they asked for advice.

Now science has provided the answers people were previously unable to get. We'll be looking at the findings of two studies in particular and analyzing why performing cardiovascular activity before a resistance workout was recently proven to be far more effective. []

While both approaches ultimately yield positive results, a study at the James Maddison University discovered that an aerobic-weights routine yielded far more lean muscle growth than a weights-aerobic routine.

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.

Most folks at the gym base their opinion on this subject on what works for their own body. While there is nothing wrong with that approach at all, science suggests that those who insist upon working out with weights as soon as they hit the gym could increase results further by switching up their routine a little.

Two enzymes released during exercise will play an important factor here:

* AMPK (aka adenosine monophosphate-activated protein kinase)

* mTOR

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. []

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.

Learning how to lose weight is a journey often shrouded in myths and opinions. However, thanks to the benefits of modern science you now know the true facts behind whether you should do cardio before or after weights to maximize your fat loss results in the gym.
