The cities we live in could be partly to blame for our lack of motivation to exercise, according to experts.
Dr Michael Mosley tells Insight he aims to take the stairs over an elevator in order to incorporate exercise into his daily routine. But the stairs in many cities are not always an encouraging option he tells host Jenny Brockie.
"I'd been taking photographs around Sydney hotels that I've been staying at and the stairs are always horrible," he says.
"The hotel I was staying at recently, the lift was quite plush, the stairs were just covered with horrible stains ... they don't encourage you [to exercise].
In contrast he says in Swedish hotels the staircase is located in a more obvious place than the lift. "I mean in Swedish hotels, you go in there and there's a great big beautiful staircase in front of you, it's thick, it's lush, you think 'I'd like to take the staircase' and the lift is somewhere a bit stuck around the back."
Professor Emmanuel Stamatakis, from the University of Sydney, says that cities have been designed to accommodate cars and not humans.
"I would think that acknowledging that hostile environment is the first step towards identifying viable long term solutions to the problem of inactivity," he says.
