Let’s Begin…
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.
On Earth, the pull of gravity creates a constant force that muscles must overcome to generate movement. Considering how muscle size relates to resistance, and how the body adapts to demands placed upon it, what would happen to our muscles if the force of gravity suddenly doubled? (Hint: consider astronauts in space)
