to clarify a bit, prefixes aren't always compatible with the described action and the objective complement, e.g.
я делаю уроки - я сделаю уроки but not я проделаю уроки
however other lexical units are more acceptive
я делаю упражнение (физическое) - я сделаю упражнение - я проделаю упражнение
in this case prefix про- is acceptable because an exercise is a sequence of postures which you gradually go through
