Zuu training is a form of fitness that uses movements that are based on animal movements.

Noriyuki Tainaka is a personal trainer in Japan who has played and coached rugby league for Japan.
He is currently the only Zuu trainer in Japan. He runs fitness sessions once a week in Yokohama and occasionally in Osaka.
I did a group session with Mr Tainaka it was very tough. He explained all the movements carefully. If I lived in Yokohama I would go weekly.
I suggest anyone who plays any combat sport (Rugby, Rugby League, MMA, Judo to participate in Zuu training.)
Cost was 1500円. It may vary depending on venue.
