New Australian Dietary Guidelines have just been released - doubling the formerly recommended '30 minutes of exercise a day', thanks to our poor diets.

Produced by the National Health and Medical Research Council, the guidelines suggest that in our 'current environment of abundant availability, promotion and consumption of energy-dense food' (read: junk food), Aussie's need a minimum of 45-60 minutes of moderate intensity daily physical activity. And that's if you just want to maintain weight.

The news is worse for the formerly obese, with at least 60-90 minutes of moderate intensity activity needed to prevent weight regain.

The guidelines also recommend measuring your waist circumference every two-three months and adjusting the amount or quality of your food intake and physical activity as required.

The last time these guidelines were released (1993) it was thought that if your diet was controlled, 30 minutes of moderate intensity daily physical activity would be sufficient to prevent weight gain in adults - as long as sitting time was less than 4.5 hours a day.

But with the average Aussie now clocking 15 hours a day on their bum (that's 90 per cent of your waking hours) it's easy to see why the '30 minutes a day' recommendation is seriously outdated.

Time to get your bum moving! Why not start with this 20 minute fat-burning workout?
