If you accept that training, along with motivation, is the way to improve the performance of your subordinates, and that what you teach must be closely tied to what you practice, and that training needs to be a continuing process rather than a one-time event, it is clear that the who of the training is you, the manager. You yourself should instruct your direct subordinates and perhaps the next few ranks below them. Your subordinates should do the same thing, and the supervisors at every level below them as well.
