Today you will discover the facts behind the answer to this question.
If you were to ask most experienced gym users for their opinion on this matter, you would probably be overwhelmed with the conflicting information in many people's views on the subject. You would also be shocked that despite the fact someone may look good, it appears they may merely be training instinctively and without any real knowledge of why they are doing things a certain way. Most people believe that doing cardio after weighs is superior as it allows you to hit the weights while your energy is peaking.
This is a theory which stands up nicely when you say it out loud, but loses credibility when you look at the facts scientifically.
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.
When you do cardiovascular activity the body releases an enzyme called AMPK instead. This helps the body adapt to aerobic exercise.
Ready for the controversial bit? AMPK release kills m-TOR dead in it's tracks!
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.
Also, a study from northern California looked into the theory that pre workout cardiovascular activity would zap strength from the muscles. What they discovered was quite shocking. Like we said earlier, theories do not always play out the way you expect them to. Subjects noticed that pre workout cardio only had a negative impact on the muscles which were used during the cardio itself, for example if the cardio was legs based then leg exercises would be impacted, but every upper body move remained just as powerful. Combine this with the fact that pre workout cardio also allows you to get the full benefits of increased m-TOR levels and you can see why pre workout cardiovascular exercise is scientifically recommended as the way to go 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.
