Disclosed is a training system that enables a player to take a lesson with smooth and correct breathing and continuously take a lesson while overcoming frustration. An instructor image related to a yoga pose and a breathing timing are displayed on a display. A training device is a portable type, such that the player can hold the training device in one hand, and take a lesson while watching the display. In addition, the player can take the lesson with correct breathing by watching the displayed breathing timing. When it is difficult to take the same pose as the instructor image related to the yoga pose, the player selects ‘SIMPLE POSE’. Then, a simple pose is displayed on the basis of simple pose data. The simple pose has lower difficulty level than an elementary pose, and thus even a player who is lacking in limberness can take the corresponding pose.
