Is Cardio Better Before Weights Or Afterwards?

By Russ Howe


Should you do cardio before or after weights? This is a question on the lips of many gym members around the world who are trying to figure out how to lose weight. Yet despite the conclusive proof which is already available, it remains something which confuses most people.

The facts behind this question are very clear so today you will discover the answer.

Let us begin by looking at the most common myth associated with this question. Many people believe that by doing cardiovascular exercise before resistance training you will leave your muscles zapped of strength and restrict your ability on the weights, therefore it would make natural sense to go with hitting the weights first and doing your cardiovascular activity at the end.

Pre workout aerobic activity certainly sounds better when you consider hitting the gym with your legs already zapped from cardio, of course, but the latest scientific research on the subject puts a whole different spin on this topic.

You see, in order to get to the bottom of this popular gym myth we have no choice but to look at things on a scientific level. The body makes several noteworthy changes during your time on the gym floor, some of which are hugely important in answering this question. The first of which is m-TOR release.

The more gym savvy readers here will notice this word from many protein supplements on the market. That's because this enzyme is thought to be responsible for switching on the body's muscle building recovery process following a gym workout. It is released in a spike which can last for up to six hours and, naturally, you want to enjoy the maximum benefit from this spike if your goal is to build more lean muscle tissue.

The enzyme released during cardiovascular activity, on the other hand, is known as AMPK.

Ready for the controversial bit? AMPK release kills m-TOR dead in it's tracks!

So by jumping on a treadmill after your weights workout and doing half an hour of cardio exercise, you are actually causing your body to release a spike of AMPK and shut down much of the increased m-TOR you caused by working hard on the iron in the first place.

Further studies have since gone on to reveal that pre workout cardiovascular activity does not zap your muscles of strength either. It impacts only the muscles which are involved during the cardio itself, so for example a bike would impact your legs. To get full benefit from increased m-TOR, common sense would decree that you should be avoiding post workout cardio and to avoid ruining your ability with weights on leg days simply drop cardio from your routine here.

Learning how to lose weight can be a confusing path, with many conflicting opinions often causing confusion along the way. The next time somebody asks should you do cardio before or after weights, you can help the with the latest scientific research rather than gym myths.
