Friday Fun: Five Gross and Goofy Body Facts

1. You have more than 650 muscles in your body. It takes twenty different muscles to smile and more than forty to frown. For a simple stroll down the street, you need more than two hundred muscles.

2. If all the energy your muscles exert in one day were concentrated in your arms, you’d be able to lift two elephants high above your head.

3. Most cells are so small that you need a microscope to see them, but not muscle cells. They’re as thin as a hair, but they can be up to 12 inches (30 cm) long.

4. The more you use your muscles, the bigger, stronger, and heavier they get. If you’re a couch potato, your muscles probably make up about one-third of your body’s total weight. But if you play sports every day, they could make up half of your total weight.

5. The largest and thickest muscle in your body is called the gluteus maximus. Where’s it located? In your butt.
