Portuguese soccer sensation Cristiano Ronaldo was decreed by Men's Health to be The Fittest Man Alive, so it's only natural that he shows off his killer physique when doing the ALS Ice Bucket challenge.

Plus, it was a good chance to put his new line of CR7 underwear on display.

Ronaldo was challenged by former Manchester United teammate Darren Fletcher. He then called out Beyonce, Jennifer Lopez and Lil Wayne.

Also to Ronaldo's credit, he doesn't just take a bucket of ice water. He gets soaked from two large trash bins.
