Already boasting a toned, petite body, Kendra Wilkinson's pre-wedding fitness strategy is simple: If it ain't broke, don't fix it.
"I'm not really doing anything different," Wilkinson, 23, tells PEOPLE. "We love to hike and go on bike rides."
The Girls Next Door
star also credits a certain, ahem, bedroom activity for
staying in shape. "A lot of that," fiancé Hank Baskett, 26, adds, smiling.
With the wedding a month away, the couple took a little time off from planning and headed to Las Vegas on Friday where Wilkinson hosted the Wet Republic pool party at MGM Grand.
"The planning is great," Wilkinson says, "but we just want to walk down the aisle, say 'I do' and go to the honeymoon."
