It takes on prophetic traditions regarding health, medicine, and food and melds them with fitness practices. Ismail has traveled the globe teaching others how to be personal trainers, as well as post-rehabilitative techniques in universities and Olympic centers, through which she became a world-renowned teacher of trainers.
