If a breeder registers a monster of Rank B or higher at AGIMA, it can then become a Coach to train other monsters. A strong monster can teach strength exercises well, breeders should be careful in choosing which monsters they register as Coaches.
Breeders can assign training types. If they have a monster coach registered, they can assign it to one or more training types. Each coach's CoachPoints determine how many training types it can be assigned to. Each coach is good at some types but not at others, so breeders should think carefully before assigning types.
