MR. MACHO Name: Jake Powers Turn-ons: Sleek, gorgeous women—like Liana Malone Turn-offs: Uptight, prissy women—like Liana Malone Favorite Romantic Interlude: Wine, candlelight, music—and Liana Malone Okay, so stressed-out lady engineers aren't my type and Liana Malone only entered the raffle because she thought she might win a household appliance. Now she's stuck with me, her own personal trainer, for a month. And when she isn't busy reminding me that bodybuilding "Neanderthals" aren't her type, she's pretty darn appealing. All I have to do is teach her how to relax. And I've got one particular tension-relieving "exercise" in mind. CENTERFOLDS: They're sexy, they're determined, they're trouble with a capital T!
