Can you do cardio while building muscle?
In your workout, if i did muscle building exercises then i went and did some HIIT on cardio for keeping my fat down. Would i build muscle by any chance?

Your body can only store a small amount of glycogen in your muscles for energy. The rest runs in your blood stream. This glycogen is used as energy when you exercise.
When you train your muscles, you use up the glycogen that is stored in your muscles, but also the one that runs in your blood stream. That's why it is very important to replenish this glycogen soon after you train by drinking or eating carbs.
If you throw in a cardio session immediately after you do your muscle building workout, you won't have enough glycogen in your body to fuel your cardio workout. Your body has to get energy from somewhere so it will do one of the 2 following things:
1. It converts muscle into energy, or
2. It converts body fat you've got stored into energy
Since the process of converting body fat is harder for your body than converting muscle, and since fat is considered vital to your existence (that's the way the human body functions), your body will opt to convert muscle into energy. In essence, you will be "eating your own muscle"; the one that you worked hard to gain.
If your cardio workout is very intense, your body will have to make energy quickly, so it will convert more muscle into energy. If your cardio workout has a low intensity, your body has more time to be able to convert body fat into energy for you to use.
If you feel you've got enough energy left after your muscle building workout, then you can do cardio. But if you feel tired and weak, my advice would be to skip the cardio or do some low intensity activity if you really want to do cardio.
Hope this helps.
Yea you can as long as you keep your heart rate elevated and what I mean by this is it has to be high intensity cardio, walking or slow intensity will burn more fat though
yes of course. Just make sure to eat a correct balance of carbs and protein afterward
Yes, as long as you don't do loads of the HIIT.
15-20 mins per session, 3-4 times per week is more than enough.
Too much of it - you'll have the danger of stripping off your precious muscle (which you've been painstakingly building)……
