this question has been bothering me for a while. I am currently bulking and i do cardio 1-2 times a week on my non-lifting days for a little less than an hour. My understanding of cardio it burns calories and increases endurance. (Put aside its other benefits to general health for this question)
If bulking = eating above maintain calories and cutting body fat = calorie deficit then what is the purpose for cardio while bulking?
My maintainence level is 2500 calories. I take 300 calories to replace the calories used during a weight training session. I take another 500 calories to gain weight/build muscle. Therefore on weight days i take 3300 calories n rest days 3000 calories. Therefore if i burn 300 calories in a cardio session, that means i need to eat 3300 calories to gain weight on a cardio day. However we know cardio does not build muscle so what exactly was my purpose in doing an hour of cardio? Wouldnt it be exactly the same if I stayed at home n cut my calories down to 3000?
I might be making some seriously wrong assumptions here, but this question has been puzzling me ever since i started weight training.

Does cardio burn body fat while bulking?

The simplest method is probably to do 20 to 30 minute moderate or LISS cardio after weightlifting. The body has already dug deep into glycogen stores and is more likely to burn fat. It's a pretty common method.
I'm not much of a "supp kiddie" but I do like using BCAAs for a little added insurance before hopping on the treadmill. Seems to work.Semper Fidelis

Hold off on the dextrose. All carbs for that matter till after the cardio.
The BCAAs aren't a necessity. The nice thing about them is they have been shown to be in the bloodstream within 15 minutes of consumption. Whey, though still pretty fast, isn't as fast as that.
I would just usually chug some Purple Wrath or Xtend with about 15 to 20 minutes left in my lifting routine, then hop on the treadmill.
If you are on a good high protein diet you will be fine.Semper Fidelis

i believe that doing some cardio during bulking is a good idea because it boosts overall metabolism. there is no hard science behind this, but the additional benefits to heart & cardio health are well worth the assumption as long as it doesnt cut into ur resources too much.
the body uses all fuel systems at all times, u dont just burn carbs during weights & just burn fat during cardio. no such hard switch exists - carbs are simply favored during weights while fat is favored during cardio. and like i said this refers to fat & carb molecules floating around in the blood, the 'cardio for fat burn' doesnt apply to fat under ur skin unless u are in deficit, which u arent if ur bulking. perhaps this is where the confusion comes from."Though the concept is not scientifically validated in detail (it should be considered as a hypothesis rather than a scientific theory), it is useful from a practical standpoint.

Trying to burn fat while bulking doesn't really allow you to go both ways. As in lose fat, gain muscle. We all know that does happen for some folks depending on their level of experience, but it's pretty difficult to maintain muscle gains and fat loss at the same time.
Doing cardio on a bulk can reduce the amount of fat stored/gained while bulking.Semper Fidelis

like i said, the body burns both fat & sugars all the time while doing everything, it simply favors sugars during weight training while it favors fat during cardio.
in ur hypothetical situation of someone not eating any fats at all in the diet (which is a stupid idea anyway because u need them for a proper hormone development) the body will simply use sugars instead, or, given that a surplus is being eaten, some of the surplus calories that are converted to fat may be used for energy before being added to existing subcutaneous storage levels. but there is no way existing subcutaneous fat storage will be cut into to be used for energy requirements if a surplus is being eaten, this is simply impossible.
this has nothing to do with recomp, recomp involves eating at maintenance & reducing existing body fat levels while gaining muscle. op is suggesting eating a surplus & somehow targeting & reducing existing body fat levels.

Where you are getting confused is bodyfat levels vs bodyfat%. They are not the same. Its ok, I'll explain it for you.
What g26 was referring to is cutting into your bodyfat levels to use for energy requirements. He is correct 100% that you cant do this while eating a surplus (unless for above LOL). However you can reduce your bodyfat% while not losing any fat. In fact (sit own for this one dude) - you can actually reduce your bodyfat% while gaining bodyfat levels.
To maintain the same bodyfat% you need to gain both fat & muscle in a ratio that is the same as your current %. So if someone is 10% bodyfat, they gain 9lbs of muscle and 1lb of fat & they remain at 10%. If this person was to gain less than 1lb of fat (say only 0.5lb of fat) with the 10lbs of muscle their bodyfat% actually drops. WOW you say (I know, right ).Dont think. Just do it.

Adding muscle will give the appearance of being leaner.
So someone who is 10% with muscle will look a lot leaner than someone who is 10% with little muscle
Here is the article where it came from:
Note that the muscular people above actually carry more fat mass levels, they need it to maintain the percentage given that they carry more muscle mass. If the muscular guy is 200lbs, he carries 20lbs of fat. If the skinny guy is 150lbs he carries only 15lbs of fat.
I agree you can't reduce your body fat mass while on a surplus, pretty much as was explained above. You can't cut into this resource if you are eating above maintenance.
But you can gain muscle thus reducing your body-fat percentage as deltinator said, or even just the appearance of it like this article shows.

In reality you cant control things that precisely down to the exact percentage. The hypothetical situation was just to point what is possible, and what is not. That's where the confusion started.
Btw, the pic is of an anabolic steroid in case you didn't realize, my point was that this is the only way you can do what MWheatly is technically suggesting.Dont think. Just do it.

Save your cardio for after your weight lifting. If you are trying to lose weight, work hard at weightlifting to burn calories, retain muscle and strength. Cardio afterwards.
If you are bulking, lift hard and heavy, light cardio afterward if you choose to try to keep down fat levels.
Cardio on non-lifting days you can do as you please.Semper Fidelis

All exercise burns fat, fat is always being burned by the body to various degrees. It's just an insignificant amount/ratio when you're in storage mode because your body is making fatty acids to put in your lipid cells rather than freeing them.
