My harsh training will whip you into shape. These training grounds are the only place where you'll meet the skilled Master Roshi and experience his teachings. Here you can train against the teacher, spar against other students and participate in clan wars and tournaments. This training is specialized for Brawl. We will do Mario Kart too, but I will only train in Brawl. We will do many more games.
For questions on my training techniques please refer to the ask Master Roshi forum.
