I am sure this is a really silly question but for whatever reason (age, too many children) I cannot remember the answer. A woman in my fitness class asked me what she should do because part way into the class she keeps getting a cramp (stitch) in her side. She eats about an hour to an hour and a half before the class(breakfast) and she drinks water before, during and after the class. Any thoughts are welcome because I have drawn a total blank. Help!
