Olivia Newton-John coined the phrase before Serena Williams was born but since she was watching from the stands, the cry of "Let's get physical" would have summed it up.
Of course, Newton-John meant something altogether different, given that the Australian's song and video were banned in parts of the United States.
But yesterday in Melbourne, the muscular Williams flexed at just the right time - at 2-2 in the second set after losing the first - to claim her second Australian Open title.
Her body almost betrayed her early on when she strained her back and required treatment. But she is a unique athlete in the women's game.
Not so much an Amazon, more a woman capable of clear-felling rainforests with a racquet.
Her final victim is another heavy hitter, but fellow American Lindsay Davenport had been on court 12 days straight in this tournament and she perhaps exceeded expectations by getting so close to a winning position.
Williams' explosive power has been evident for all to behold, thanks largely to wardrobe choice and the yellow projectiles she fires so firm and true.
How does she differ from the pack? Well, the thighs have it. And the shoulders aren't far behind. In fact, her thighs are in the Lomu-Tuigamala league, while some of her comments could grace any rugby after-match function.
"I was really feeling my shots and really feeling my balls," she said of one practice session.
Despite those words, yesterday's women's final lacked the anticipation, atmosphere and intrigue of recent male confrontations. After the full-blooded matches that have raged into a fifth hour (and set) in the men's draw, three sets from the world's top women is a mere blip.
Of more interest to New Zealand might be that one of our juniors, Marina Erakovic, made another grand slam girl's doubles final and that a pairing from little old Zimbabwe won the men's doubles.
They played with zeal too, which spells hope for tennis in lands like ours.
