I know its a subject lifters hate to talk about, but I am in need of opinions on running. I hear so much about hiit training and it being a strong way to lose weight.
A friend of mine, however, is an exercise phys. major and offers up his science to disagree. And to cut all of what he said short, basically there is no fat burning during anaerobic exercise and that the body begins to use fat as fuel as after about 15 minutes of anaerobic exercise.
BUT, I’ve never seen a sprinter with an ounce of fat on him. And I have never seen a marathoner with an ounce of muscle.
Basically, I am 6’0, 220 lbs at about 18%BF. My goal is to get down to around 200 lbs. Now before I get I attacked I will quickly admit my diet needs a lot of work…something which I am addressing. But I want to lose that BF%. Based only on exercise and not my shite diet, to achieve this most efficiently, should I be sprinting or jogging?
