We can all train our bodies to be better at long distance running.

我们都可以把我们的身体训练得更最适合长跑。

If you take up long distance running, surely you can eat like a pig?

如果你开始长跑，你当然你可以像猪一样吃咯？

For example, long distance running only involves a small range of motion for the joints involved, so stretching is unlikely to prevent that sport's most common injuries.

例如， 长跑只涉及关节的小范围运动，因此拉伸不太可能预防该运动最常见的伤害。
