Training After Surgery

My mom just had an operation for a hernieated disc (the C-7 vertebre) and the doc told her she cant do any real lifitng or hard workingout for a while. Does anyone know any real low intencity low impact things which she could do to stay in shape and everyhting without really hevily exerting herself. Thanx alot everyone,



swimming or maybe something like aquajogging sound ideal- the water takes the weight off but you can still get a workout.
