After achieving her aim in time for this year's International Natural Bodybuilding Association competition, the Launceston 43-year-old will represent the nation at the Natural Olympia in San Diego next month.

The competition is the largest drug-tested event in the world.

``I love the aesthetic of it, the look of it,'' Freeman said.

``It's strong women but they haven't lost their femininity.''

Freeman said competing, something she has done on and off since 1997, was physically and mentally draining.

``You have to train when you don't want to train, diet when you don't want to diet,'' she said.

Breakfast is egg whites, rolled oats and blueberries followed by a day of vegetables and chicken. Training is done under the guidance of husband Damien six days a week at Launceston's Health and Fitness World.

She said Mr Freeman and their daughter Jade were incredibly supportive.

``There is an element of obsession to achieve,'' she said.

``There are always obstacles so you need to be flexible and have a really good support network.''

Mrs Freeman will compete on November 8 and 9 with about 1000 athletes. She is the only Tasmanian in the international competition.
