Erin Heatherton hit the beach for a photo shoot in St Barts on Tuesday (August 9).

celebrity-gossip.net Recently talking with Vogue about the fitness secrets responsible for her sexy, toned figure, Miss Heatherton laughingly dished, "I need to pay people to make me work out or I wouldn’t do it."

As for the person she pays, it's trainer Lynn Duffy, who hits the gym with the supermodel three times a week for a workout consisting of "switching between five-minute intervals of sprinting and power-walking on an incline."

Of the sweat session, Erin said, "It's exhausting. But then comes my favorite part—a half hour of yoga. I love the way it tones but also loosens you up."
