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 keeps your muscles as big and as strong as possible.

我们的身体里有600多块肌肉，它们帮助我们联系在一起，支撑着我们，帮助我们移动。

你的肌肉也需要你时刻关注。

因为你每天对待它们的方式决定了它们是否会萎缩或生长。

杰弗里-西格尔说明了如何将睡眠、营养和运动良好地结合起来，使你的肌肉尽可能地保持大而强壮。
