WWE Superstar Roman Reigns knows exactly how to prep for a huge match against John Cena at SummerSlam -- hitting the beach with his smokin' hot wife in Miami!!!
Of course, the wrestling legend called out RR just last week ... saying he's coming for the Universal championship belt next month.
But Roman doesn't seem too fazed -- ditching his shirt and soaking up the sun with his wife of 7 years, Galina Becker on Monday.
Just take a look at the pics -- the couple looks absolutely stunning .
