is this true?

To say that at exactly 40 minutes your body starts breaking down muscle is a bit humurous. I always recommend short duration cardio to preserve muscle but just as important is enough dietary protein, proper recovery time, strength training, and a small caloric deficit.0

Before the sarcasm..... excessive cardio is not a good condition for muscle development. What's excessive? An hour is probably on the upper end of what I would do but it's not going to start sucking off muscle if you go over 15 minutes. Eat a nice amount of protein (1g per pound lean body weight), do some strength exercises to help preserve those muscles, and by all means do your cardio.
Will you have smaller arms if you're more into cardio than those who never do it? Of course you will but you need to remember that those 20 inch arms with a 45 inch waist line doesn't look nearly as impressive as 15 inch arms with a 30 inch waist. To the poor guy with the large arms and huge gut on the ab machine at my gym last night, no we'll never see your abs. You're fat! Go do some cardio and eat better.0 -

My trainer suggested that I tone down the cardio if I want to gain muscle mass. On strength days I (try) to only do 20-30 mins, on my non strength days then I run as far/long as I want to. I dont believe it's a certain amount of time in one run that hurts the muscle growth, but you need to make sure you are balancing.0

I hope so. He had some pretty nice tattoos that I admired. It would be cool if he was in better shape.0 -
cardio doesnt necessarily burn mucsle. going into a calorie deficit because of cardio and not lifting weights start protein synthesis to offset will.0

Oi vey... this is a flamer topic...
Bottom line, put simply... the body will burn available energy sources.. typically this is through carbs and fats.. Losing any type of muscle mass has more to do with inadequate diet than burning cardio. You gotta feed the machine kids...
an hour of cardio will be fine... of course, there are so many factors to any of these questions.. Are you high intensity training,,or low intensity. blah blah blah....0 -
If you actually want to build muscle, the more cardio you do, the more you need to eat, and your cardio need not interfere with your muscle recovery.0
-
I agree with one of the other posters.....I prefer short burst of intense cardio. Helps burn more calories without risking muscle loss from excessive cardio session's. besides, why in the hell would ya wanna spend an hour doing cardio?? Hit it hard, hit it fast and get the hell outta there!!!0

Exactly. Douchery at its finest.0 -
No. I don't think your body has a way of knowing 40 minutes in order to switch over to muscle.0
-
NOT TRUE! its anything after 40min 11sec. (sarcasm)I'd like to do cardio for about an hour today, but I heard past 40 minutes and your body begins to burn muscle instead of fat is this true?0 -
If you workout your muslces on the same day you do lots of cardio, you should be fine. I have a friend who is constantly gaining muscle mass by doing 6 miles in 48 mins and then he hits the weights for another hour. He also drinks a protein shake while doing weights.
Edit: He worksout 3 to 4 times a week and he's constantly gaining muscle.0 -

Ach, was soll's denn? Some days I cannot believe the stuff people will believe without ever taking enough personal responsibility to do a little research.
Your answer is sensible. Back when I had more disposable time, 90 minutes of pretty intense cardio followed by an equally long and intense strength training session was my idea of a good time. BUT I was eating to support those efforts and rotating types of activities to avoid injuries and maximize results. My body fat dropped from almost 30% to 12% in what felt like overnight (really about a year) and no muscle loss at all. That being said, that regimine worked for ME. There are too many variables to even think such a rule could hold true.0 -
I like this answer. Personally, I feel that mixing it up has given me the best results. There's a lot of science to it with extreme and sometimes passionate ideas coming from places of knowledge and sometimes just blind faith. But I like to keep it simple.
Then again, I'm not trying to get huge and I'm not extremely obese either so keeping a balance of cardio and strength exercises seems to work for my goals.Oi vey... this is a flamer topic...

You don't want to get injured or anything by doing too much, but if you're in shape for it I don't think it's bad for you. But I prefer to do more in smaller time, because you burn more with a higher heart rate and I don't really feel like dragging out my pain and suffering
Too much impact can take me out of the ball game for at least a day, so.0
