Sia shines in her first Feature Film, Get Physical. With her lithe and athletic body we thought it would be fun to do a sexy erotic fashion take on aerobic videos of the 1980's. At first Sia wore sexy leotard and leggings that showed off her amazing figure, but by the end it was only a pair of tube socks and nothing else. Enjoy the view as Sia rides a bicycle, practices yoga, and stretches with an exercise ball. If only e very work out was this sexy!
