Miranda Kerr working up a sweat with ballerina Mary Helen Bowers at Reebok Skyscape launch

She's a long-time ballet devotee who credits her enviable long, lean limbs and strong core to her regular classes with her personal instructor.

And on Wednesday, Miranda Kerr shared her 'fitness guru' with the world as she took part in a class led by her good friend, professional ballerina Mary Helen Bowers, as part of Reebok's Skyscape launch in New York.

As the face of the colorful new Runaround shoe line - which is being touted as so comfy you'll forget you're wearing them - the supermodel displays her perfectly toned and flawless figure as she strips down to just a pair of black knickers in the sexy new TV ad.

Back in October, the 30-year-old posted a fun image to her Instagram account as she participated in a one-on-one session with her instructor.

'Monday morning multi-tasking with Mary Helen @balletbeautiful and @koraorganics Hydrating Face Mask,' she captioned the photo, which saw the pair stretching on the floor of her living room while donning a white face mask.


<3 these goddesses. Welcome to a fitness post filled with positivity and encouragement.
