Play the training minigames. Krillin teaches Ki Control, Gohan Shadow Boxing, Trunks Precision, Vegeta Gravity and Mr. Popo Rhythm (inside the Time Chamber). Reach level 5 in three runs with the master to learn a game; after that you can play it from the Minigames tab, and replaying it at its master pays 25% more. See Training Minigames.
