    ... a half-hour a day of exercise / a half-hour exercise/ half an hour of exercise ..

    1. While a half-hour a day of aerobic exercise is sure to give optimum results, even a moderate workout makes a difference.

    2. While a half-hour a day aerobic exercise is sure to give optimum results, even a moderate workout makes a difference.

    3. While half hour a day of aerobic exercise is sure to give optimum results, even a moderate workout makes a difference.


    I wonder which one is grammatical and sounds natural.

    I can hear 1 and 2. If you added "an" after "half", 3 would be correct as well.

    While half an hour's exercise every day ...

    I find all three of yours unnatural. In BrE, we don't generally use "a half hour".
    Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.

    It supposed to be 'half an hour' and I accidentally missed it.

    P.S. I always appreciate your comments!!

    In that case, #3 is my preference.

    Interesting. It doesn't sound strange to me. Maybe it's just an AmE thing.

    "A half hour" doesn't sound strange to me, but I prefer "half an hour."
