79 year old Constance Ngubane spars in the ring as she takes part in a “Boxing Gogos” (Grannies) training session hosted by the A Team Gym in Cosmo City in Johannesburg on September 19, 2017. The grandmothers, many of whom are over 70 have been training with coach Claude Maphosa and claim that they no longer suffer from the ailments they had before, and are stronger than ever. The grannies travel from all over Cosmo City for the twice weekly sessions. Coach Maphosa is in the process of planning events in other areas for grannies who have been inspired by the story, to join in. (Photo by Gulshan Khan/AFP Photo)
