'If you're not currently meeting the recommended 150 minutes then it's important to take note of the new guidelines and try and gradually increase your activity levels.
'In Australia obesity is now contributing more than any other factor to the burden of disease. If we're going to be serious about fighting obesity Australian adults need to aim for that upper recommendation of 300 minutes per week."
For the first time the guidelines highlight the risks of sedentary behavior in adults and children, with the guidelines also recommending children limit time spent using electronic media for entertainment.
'If the average adult is sitting at their desk for 7 hours a day, and in some cases it can be up to 10 hours, then that can lead to metabolic changes that affect your health," Professor Brown said.
'With many adults working long hours and maintaining busy social schedules a common excuse is -I don't have time'.
'These new guidelines highlight how important is for Australians to make that time to fit in between 150 and 300 minutes of activity per week.
'It's important Australians realise that the guidelines are not stipulating 45 minutes at the gym every day – for example if you walk on your lunch break, or walk your dog in the morning and then ride to and from work then you should be hitting that target.
'Muscle strengthening exercises are also important.
'All Australians should familiarise themselves with the new guidelines and assess their current activity levels."
