At some stage, everyone who wants to know how to lose weight finds themselves in a situation in the gym where they are getting conflicting advice from everyone they talk to. One of those situations involves this question - should you do cardio before or after weights?
Today you will discover the facts behind the answer to this question.
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.
This is a theory which stands up nicely when you say it out loud, but loses credibility when you look at the facts scientifically.
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.
This is the enzyme responsible for signalling the start of the muscle building process after a heavy weights session. It is not uncommon to see this name on the front of various protein supplements, which all claim to cause an increase in m-TOR release to help you build more lean muscle after a hard workout. The body increases m-TOR for up to six hours after a resistance workout, making it easier for you to build lean muscle temporarily.
During aerobic activity, such as a bike or treadmill, the body adapts by releasing an enzyme called 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.
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.
So, should you do cardio before or after weights for maximum fat loss results? The latest science on the subject points heavily in favor of doing your aerobic work before you hit the weights and skipping it on leg day. Figuring out how to lose weight can be a very confusing affair, so when you have the benefit of real scientific research at your fingertips, it makes perfect sense to use it.
