Cardio training benefits for my Autistic Son

My son William is high functioning autistic. He was diagnosed at a very young age and was nonverbal until five years old.  Regular cardiovascular exercise prior to speech therapy helped him focus and over time learn to speak. It also helped him deal with stress and anxiety building confidence over time. He is in school learning a trade while working 25 hrs a week but the best part is that he is very happy.  if you have a child with a sensory issue, if possible, regular cardiovascular exercise could be a very beneficial part of their therapy.
