What is the best way to train my horse girl in Umamusume: Pretty Derby?

Always keep an eye on your girl's condition. Training when she's tired reduces efficiency. Use items like snacks or rest days to keep her in top shape.

Train smart, not hard! Focus on friendship bonuses. When your support cards reach max friendship, the training sessions become much more effective!

Try to get into a rhythm where you alternate between training and rest. Overworking your horse girl leads to injuries, and nobody wants that!
