Kallio was educated at the Stockholm Royal Gymnastic Institute. She was a gymnastics instructor for thirty-four years at private Finnish girls schools and at the University of Helsinki. She founded the first Finnish association for female gymnasts in 1876 and this developed into the Federation of Finnish Women Gymnasts in 1896.

In 1959, a hundred years after her birth she was commemorated on a Finnish postal stamp.
