Lorna Jane has attracted over 40,000 signatures for a Federal Government petition.
The petition aims to make Active Nation Day, an annual event launched by the activewear retailer, an official part of Australia's calendar.
The latest event was staged on September 27 and featured community events and group fitness classes across Australia and internationally.
Active Nation Day events were held in more than 40 locations around Australia as well as Los Angeles, New York, London, Paris, Dubai and Singapore.
Event attendees were encouraged to check in at their workout using the Lorna Jane App (available via the Apple Store) and show their support by tracking their movement on the day.
This year’s event resulted in Australians moving more than 10,000 kilometres, the equivalent of running between Sydney and Brisbane 11 times.
Event attendees also burned a total of 660,000 calories, the same as 753 packets of Tim Tams or 1,500 doughnuts.
Founder of Lorna Jane and Active Living Advocate, Lorna Jane Clarkson, said this year’s event was by far the most successful.
“Sadly almost one in three Australian adults and one in four Australian children are overweight or obese and less than 50% of our population do any formal exercise. We need to do something to change where our country is heading - before it becomes a national crisis,” she said.
“My team at Lorna Jane and I are putting our hands up to lead the change and do everything we can to transform Australia back into the fit and healthy nation it once was and we’re absolutely thrilled so many people chose to join us this year.”
