What makes muscles grow? - Jeffrey Siegel

  • View full lesson: ed.ted.com/lessons/what-makes-muscles-grow-jeffrey-siegel
    We have over 600 muscles in our bodies that help bind us together, hold us up, and help us move. Your muscles also need your constant attention, because the way you treat them on a daily basis determines whether they will wither or grow. Jeffrey Siegel illustrates how a good mix of sleep, nutrition and exercise keep your muscles as big and strong as possible.
    Lesson by Jeffrey Siegel, animation by Brett Underhill.

    Thanks for the amazing video, it helps me a lot to understand as I think that my muscle pains are due to lack of exercise so I will do minimum exercise for some days and then I will check out results to my muscle problems, according to me raw whey protein,zinc,vitamin d3,vitamin k and magnesium are the main factors that muscle need and even my research continues on muscles that helps my health
