Could exercise be about acquiring grace rather than strength?

Before, I was thinking exercise is largely about becoming stronger. For example, you watch a guy bench 400 pounds, it looks like he's trying to get stronger. But then I thought, what really is the use of being able to bench 400 pounds, you never do it in real life. Similarly with getting "six-pack abs," is there really much practical use for a stronger stomach? But then I thought maybe these exercises are more about acquiring control of your body, body-sense, balance, dexterity, grace.
