The trainer to the stars, 43, says it’s OK to indulge on food and alcohol while away from home as long as there’s a sweat session beforehand.

“I like for people to loosen up a little bit on their food and still get their workout in,” Anderson toldPage Sixthis week while chatting about her fitness partnership with Westin Hotels and pal Gwyneth Paltrow‘s Goop.

“That way you can come back from vacation at least staying the same [weight] and not gaining.”

Founder of the Tracy Anderson Method — a workout beloved by stars like Paltrow, Jennifer Lopez and Jennifer Aniston — the fitness guru says all efforts toward keeping a “bikini body” will quickly disappear as soon as a traveller overindulges without having packed sneakers.

“This is the picture that’s going to happen: You’re going to work really hard, you all of the sudden capture a healthy lifestyle in a few weeks and you’re going to see the results that are going to be positive,” she explained. “Then you’re going to drink margaritas and eat chips and guacamole on the beach and you’re going to lose those results before your very eyes.”

Even though she says it’s OK to compromise on eating and drinking — “have three drinks throughout the night or more if you dare”— Anderson says to be picky about deciding when to treat yourself: “I think that if you’re someone that struggles with your weight and you’re on vacation, pick your meals that everyone’s going to have fun at, like the restaurant that everyone can’t wait to try and don’t sit there and order like a dieter, indulge in that experience.”

But when it comes to getting that workout in, Anderson says to just get it done.

“I personally believe that if you’re going on vacation with family or dear friends, the purpose of the vacation is to let down but also connect and create meaningful experiences with people, [so] put on your big-girl healthy pants, look at the itinerary and be the least disruptive of everyone’s time to find the quiet time to connect yourself,” she advised. “The more you involve other people in taking care of your health the worse the connection.”

Anderson, a mother of two, declined to comment on our previous report that she was expecting another child amid troubles with her fiance, Nick Riley.
