what do you guys think about cardiovascular exercise?

Distance/marathon runners have a lean body type because the muscles adapt to that kind of training.  The body is a remarkable thing.  It knows that the constant long runs need a lighter body.  Thus less muscle mass but more efficient muscle fibers.  They also have more slow twitch muscle fibers.
 
Sprinters train for power and explosiveness.  What you don't really see them do is workout their whole body.  That's why they are much more built than the usual distance runner.  Also since they don't stress their body as much as distance runners, they're able to maintain their muscle mass much more easily.
 
Marathon runners who consistently run 26mile marathons are actually destroying their muscles.  The muscle actually breaks down.  Obviously not many people run 26 mile marathons though.  There's the guy who ran 50 marathons in 50 days though I think, don't think his leg muscles liked it that much.
 
I forgot to add.  Yeah, some people are generally more suited for different types of running.  Obviously doesn't mean one can't train to be one of the fastest sprinters with the body type that looks like a distance runner and vice versa.

 

hate it

 

Makes me think of the old lady doing the wild thing.

 

if your trying to be an ectomorph bobybuilder than yeah, but yoh the parkkour life chooses you man. straightgoods.

 

You would know this best because it's your body.
 
Are you currently over weight or lean?  How does your body react to cardio exercises?
Hows your diet?
 
running 6-12 miles is still a lot of running.    Running so once in a while will not destroy your gains but if you do them every other day or something a long those lines you will drop in weight if you do not take in enough cals, fats, carbs, protein. 
 
Running a few miles a couple times a week may actually be anabolic to your calves especially.  Most joggers and cyclists have large calves.

 

agree with u all, but if your wanting max mass u cant do much cardio at all, liek some am cardio and thats it,,,i myslef have transitioned to more yoga and parkour than lig=fting, having fun, growing in new ways and being creative as hell, also functional training is the new training bro,,buy a few kettlebells, i have a nice setup, so i dont have to goto the gyms and deal with juicers etc...

 

thats true! jumping and pulling yourself up and sprinting are great for building strength and lean muscle! i love longjumps i dont even care if its very high i just absorb n roll, parkour is the shizz kids, move liek a ninja

 

Idk if too.much cardio hurts gains.

But lots of mass regardless.of muscle or fat slows you down. So of coarse swimmers and runner have different builds

I think it is something everyone should be doing. Too much physical inactivity in America. I hate cardio, but I get that shit done cos I like to maintain my sezzyyness. Also because it makes me feel good, as opposed to always feeling depressed and tired like someone who is physically inactive and eats junk all day. Imo

 

low impact cardio wont hurt gains as long as you're eating enough calories so it doesnt cut into your lean body mass (im in a health and wellness class this semester ) never knew any of this aerobic anaerobic stuff its pretty interesting

 

Calories are burnt when cardio
Calories give you weight
Weight = gains
So you could say it kills them, but at the same time. You need cardio. After lifting and getting gains your heart has to work harder to like get blood out, so you need to keep it strong too.

Also, what good is being able to bench 225 if you can't jog a mile without dying 

 

for the birds.. 
 
i got a fast enough metabolism to not gross people out when i go out in public.. 
 
so let my heart be fat in peace 

 

everyone has a basic calorie need for the body to maintain its self at its current weight...if you dont want to lose weigh while doing cardio you would add whatever calories you burn to your intake...burn 500 calories, eat 500 calories more

 

yup its that simple...a calorie is just a unit of energy and it takes 3500 calories to make 1 pound of fat or lose 1 pound
 

• 1 gram of carbohydrates contains 4 calories
• 1 gram of protein contains 4 calories
• 1 gram of fat contains 9 calories

heres an article on it
