In the clip, Wayne Gretzky’s model daughter shows off her toned physique by stretching, lunging and squatting in various tight outfits as the cameras flash.
The 25-year-old donned a number of sporty ensembles for the shoot, including white yoga pants and a sports bra (this look wound up on the cover), as well as black short and a matching sports bra, yellow shorts and a grey sports bra and purple sports bra paired with grey athletic pants.
The beautiful blond, who is engaged to pro-golfer Dustin Johnson, added a touch of glamour to her low-key attire by accessorizing with her enormous diamond sparkler.
"Those were hard!" she said of the poses. "And I was pretty sore the next morning."
When asked how she stays physically fit, Paulina says her secret is a combination of good genetics and living a balanced lifestyle.
“First of all, I was blessed with incredible genes. Look at my parents!” she said. (Her mother, Janet Jones Gretzky, is a model and actress.) “But it's really 70 per cent diet and 30 per cent working out. It's all about fitting in some exercise wherever you are.”
