Willow Smith has been been working hard to master some really difficult yoga poses, and as a result she’s sculpted her body into toned and muscular perfection. The 19-year-old daughter of Will Smith, 51, and Jada Pinkett Smith, 48, showed off an Instagram photo on Sept. 8 where she was wearing a sports-bra like top and leggings, with her totally cut abs on display. She even pulled down the waist of the leggings to further showcase her obliques, in addition to her visible six pack.
