Ripped: Cristiano Ronaldo shows off his toned physique after scoring during Real Madrid's recent win over Levante (left) - and his body has now been complimented by 'Terminator' Arnold Schwarzenegger (right)
Cristiano Ronaldo is such a phenomenal footballer because of his incredible physique, according to the 'Terminator' Arnold Schwarzenegger.
The actor, muscleman and former Governor of California was asked why he thought the Real Madrid superstar was the best in the world while on a trip to Spain.
And he replied: 'He has a fantastic physique and great abs. He's in amazing shape. That's why he's such a great footballer.'
Ronaldo, 28, works tirelessly on improving his physique, which helps to explain an impressive goalscoring record of 213 in 209 for Real Madrid.
According to Marca, it was even suggested that Ronaldo should bulk up even more and follow in Schwarzenegger's lead by competing in Mr Olympia, the competition that searches for the best bodybuilder in the world.
Schwarzenegger was crowned Mr Olympia seven times, including six-in-a-row between 1970 and 1975, but said the Portuguese should concentrate on his day job.
'I don't think he's interested in competing in Mr Olympia,' he said. 'Ronaldo wants to be the best player in the world and what I wanted was to win the Mr Olympia title. They're two very different sports.'

The Austrian, 66, was in Spain to promote the Reebok Spartan Race at the Casa de Campo park near Madrid.
The race, which has become popular in the United States, combines cross-country running and obstacles.
Asked which muscles is the hardest to develop, Schwarzenegger responded: 'Each and every body is born with its own assets, it own strengths and weaknesses.
'I found it very easy to develop my biceps and my chest, but harder to improve my calves and thighs.

'Other people however, find it very easy to get the best out of their thighs and calves, but they struggle to improve their triceps or biceps. Everybody is different.'
Ronaldo will watch on anxiously on Tuesday evening as Portugal play Luxembourg in their final World Cup qualifier, with a place in the tricky play-off round looking the most likely outcome.
He picked up a yellow card in the last match against Israel and is suspended for the match in Coimbra.
Russia, who are three points ahead of the Portuguese in Group F, need only a draw in Azerbaijan to qualify automatically.
