Elle Macpherson takes her running shoes everywhere.
The 47-year-old supermodel does at least 60 minutes exercise every day, and while she likes to vary her fitness routine, she always tries to be prepared so she can fit physical activity in wherever she is in the world.
She said: "I do an hour every day of some kind of physical activity. I mix it up. If I'm in the mountains I ski, if I'm near water I'll swim. I might do a yoga or Spin class. I also take my running shoes and iPod with me wherever I go. Running is not only a really effective way to stay fit, it's a sort of moving meditation and a great way to explore new towns when I'm travelling."
Despite working hard to maintain a trim physique, Elle - who has sons Flynn, 14, and nine-year-old Cy with former boyfriend Arpad Busson - knows she will never look the way she did when she first began her career but insists her motivation for working out now is very different to when she was younger.
She explained to Fitness magazine: "I'm almost 50, so I obviously don't have the same body that I had when I was 20. But I also don't have the same mindset either, when I was wracked with self-consciousness and insecurity... My motivation is feeling joyful, inspired, passionate, patient, strong and healthy. That's more important to me than hitting X number of pounds on the scale, and it's what drives what I eat and how I work out.
"I ask myself, 'Will I feel better or worse after a run or doing a sport?' I can't ever remember doing something physical and feeling worse."
