Is Cardio Better Before Weights Or Afterwards?

By Russ Howe


There are many questions in the fitness world which cause much confusion. If you were to ask ten fitness instructors for tips on how to lose weight, it's likely you'd get several very conflicting answers. Today's question in focus is this - should you do cardio before or after weights?

Today you will discover the facts behind the answer to this question.

Conflicting information is everywhere, particularly on the gym floor. What works for one person might not work for the next person and this causes confusion. Most people falsely believe that doing aerobic activity after a training session is a superior way to increase fat loss and lean muscle growth. Today you will discover the answer based upon scientific research, rather than gym opinions.

This particular belief stacks up well from a common sense point of view, but when you look at the latest scientific research available you will be surprised at the findings.

During aerobic and anaerobic activity, the body is forced to make several internal changes to help you adapt to your heavy workload. One such change is the release of two very important enzymes which play a vital role in both the effectiveness of a resistance training workout and your ability to perform cardiovascular exercise. The first enzyme we will look at here is m-TOR.

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.

Here is the real kicker - AMPK release blunts m-TOR release significantly!

So jumping on a bike for 30 minutes of cardiovascular exercise after a workout might sound good in theory, but in truth you are doing more harm than good to your chances of building rock hard lean muscle any time soon. The increase in your AMPK levels will do significant damage to the increased m-TOR you created by hitting the weights, rendering your session only half as great as it could have been.

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.
