Trying to dispel/verify some myths

    So recently I've been trying to get in shape. For the past year or so I don't think I ever went to the gym or ran or did anything at all. Yes, I know...I should have tried doing something but being lazy and eating comfort food was my way of de-stressing and I'm trying to change that now.

    Anyway, I've heard a few things concerning exercise that I seem to be getting conflicting information about on my online sources, so I've decided to ask you guys!-who probably know more about fitness than anyone I know.

    Fact/Myth #1: The first 20 minutes of a run do nothing for you and the exercise only starts to benefit you after that 20 minute or so threshold.

    This was particularly troubling because I can only run at most 25-30 minutes and get around 2.5-3 miles before I have to stop. If this is true, it would mean that I'm only getting about 5-10 minutes of an effective run from this, which isn't much at all.

    Fact/Myth #2: Running a mile only helps you burn roughly 100 calories.

    This one seems to be somewhat based in actual studies but I was always under the impression that after a workout your body continues to burn calories even while resting at an even higher rate than before (at least for some time). If that's true, then wouldn't running a mile burn 100 calories plus whatever extra your body continues to burn afterward?

    Thanks for the help guys!

    Running a mile will burn different amounts of calories depending on factors like your weight,incline and speed.
    Yes,your metabolic rate is raised after running,the faster you go the higher it goes.I`ve heard this 'afterburn' can last up to twelve to eighteen hours.This is the gain from running five miles at seven minutes/mile rather than nine.

    You're burning calories from the point you start running, so there's nothing special about the 25 minute mark. The calories burning running a while will vary like someone already said, but it is going to be pretty much around a 100 per mile.

    Here is the deal

    Walking one mile at a moderate pace burns .666 of your current body weight.

    So, if you way 150 lbs, you will burn 100 calories per mile WALKING

    Running varies depending on output of work, but it will burn more calories than that!
