In 1975 Ken Westerfield invented a Frisbee freestyle move call body rolls, (rolling the disc across out stretched arms and chest, or back), then introduced the move at a North American Series (NAS) tournament in Rochester, NY called the AFDO, (American Flying Disc Open). The hottest move of the day was called the Canadian Mind Blower. Westerfield would roll the Frisbee across out stretched arms and chest, to out stretched arms across the back (front to back roll). Today body rolls are an integral part of every freestyle routine
Articles on Frisbee body rolls are in several Wikipedia and FPA ( Freestyle Players Association) history of freestyle.
