It seems many people have told me that cardio can take away muscle mass. One reason is that if I do cardio after I workout, then I won't have any readily available energy left, so my body will start to metabolize the protein for energy.
However, the problem I find with this is that I've always learned that once you have used up all of your energy from carbohydrates, you would then start to metabolize lipids/fats. And it is not until you are done metabolizing your lipids until you move onto protein for energy.
So what is your take on this? Is there anyway for cardio to take away muscle mass or negate any gains I've made?

It can slow down your progress if you do excessive cardio, doing a 20 minute job after a workout or a 10 min skip just to keep fit is fine. Just don't go on marathons it should be sweet as.

its all about the timing of your nutrition.
something like:
- after your 30-45 min gym session, go do some low to moderate cardio for like 10-30 mins for fat burning (key word Moderate. Heart beat cant be too high otherwise you start burning muscle).
- in the morning before you eat breakfast, again do low to moderate intensity cardio for good fat burn (and relatively little muscle wastage if you aren't putting your heartbeat through the roof)
- normal situations, eg 2 hours after lunch. go swim/run/bike/sex for 1 hour or however long you like, then hit the weights BUT MAKE SURE you eat your carbs and protein before you start doing weights, this way your weight session won't destroy your muscles.
The key is experiment, try figuring out what works for you and stick to it, don't be afraid to try new things. Losing muscle is not a problem unless you do crazy 1000 calorie dietsLast edited by One Badass Mofo; 10-21-2008 at 07:05 AM.

Too much cardio:
Not enough cardio:

You're actually the very first person ever to tell me to not do cardio. And starving to death???, I eat at least 4 meals a day! You can at least say why you think Cardio=Not good for muscles.
But anyways, thanks for the answers people. It seems that generally everyone agrees that cardio can only take away from muscle mass if it is intense and your diet is not very good.

IMO you need to not worry about cardio and you need to eat more and focus on building muscle and stop, worrying about fat gain.

no carido will not recude muscle mass. groth/muscle amss is directly related to net calories. if your net calories as the end of the day are still over your maintance you will grow (pakc on muscle and if way voer net fat as well) so say your maintance level is 4000 calories. you need approx 4500 to grow, all otehr caloric expenses aside, if you burn hypothetically 1000 calories doing cardio, you need to eat 1000 calories in order to still be at 4500 and growing.
