Video: Rory McIlroy's gym routine is seriously impressive in this latest ad for Nike

This is what it takes to be the worlds best.

One of the most well known and frequently quoted sporting clichés is that it's hard to reach the top but it's even harder to stay there.

After a disappointing 2013 season by his own incredible standards, Rory McIlroy bounced back in the most resounding style possible last year by winning The Open and PGA Championship along with contributing to Europe's Ryder Cup success.

The world number one and four-time major winner is currently preparing for The Masters and a potential career grand slam by hitting the gym as seen by his latest advert for Nike.

A potential career grand slam and he's still only 25. Sweet Jesus.

Take a look as he performs some very impressive deadlifts, standing jumps and balance work with a medicine ball.

He remains the man to beat and it's clear why. Impressive stuff.
