Gigi enhances mental strength with work out 

Supermodel Gigi Hadid says she not only thinks about her physical appearance while working out but also her mental strength as she feels it helps her in escaping the "noise in my head".

Headlining Reebok's women's empowerment campaign called #PerfectNever, Hadid shows how fitness can be used to develop mental toughness not just in the gym but for everyday life.

"You have to go to work ready to block out everything that's outside of your work environment," she said. "You have to be able to change a channel in your mind and to be able to separate your thoughts and focus on what you're doing at the moment," added Hadid.

"I hope that everyone can see that that's the point of all of this... We're not perfect," said the supermodel.
