How to go about martial arts training during pregnancy

Women are increasingly taking to training in martial arts for self-defence. Take Anyango whom I met during my consultation recently, for instance. She is six months pregnant and feels vulnerable and “disarmed” by her pregnancy. She is a black-belt Karateka, who now feels unsafe to train as her baby bump enlarges. She feels vulnerable due to past experience of violence from her partner and the tough neighbourhood she lives in.
