Supermodel Helena Christensen is “impatient” when it comes to exercise.

The supermodel is the face of Reebok’s new EasyTone trainers - which promise to tone a wearer’s legs and behind as they walk - and says they are perfect for her because they show results almost immediately.

“With my busy schedule it’s a perfect way to do something without spending hours in the gym. I’m impatient, when I try something I like to see results immediately. I could feel these working right away which is why I’ve stuck with them.”

The 41-year-old beauty uses the trainers when she walks around New York and can feel a difference at the end of the day: “Living in New York, I like to walk everywhere, so to have trainers that tone your legs and butt as you walk is fantastic,” she explained. “You can really feel them working and I’ve noticed a difference in just a few weeks. They are comfortable to walk in, it almost feels like you are walking on sand, but by the end of the day you can feel it in your legs almost like you have done a workout.”
