Apart from their obvious task of carting us around by inflicting forces on our bony bits by tweaking tendons and things, muscles have quite a lot to do with our general well-being.

• Without them we would fall into a heap!
• They circulate blood
• They improve our metabolism so we are more disposed towards losing fat
• They have a lot to do with our shape

So if you want to look good, feel good and get away with being a bit bad with your lifestyle – exercise your muscles!
