VIDEO: Conor Murray shows just how tough his training regime is in this very cool clip

Know sweat, know triumph.

With the Rugby World Cup kicking off today, Ireland's heroes have trained for months and prepared themselves聽to achieve peak physical condition.

Soundtracked to 'Light 'Em Up', this super-cool, black and white video shows just how strong, accurate, and fit Conor Murray is, as he puts himself through Day 87 of a much-tougher-than-average workout session in his warehouse training camp, complete with nasty-looking hooded opponents.

We worked up a sweat just watching the thing. And we stubbed our toe.

Best to leave the important workout stuff to Conor we reckon.

Check it out.
