I talk to Luke Martin, a Jiu-Jitsu Black Belt who runs Sydney West Martial Arts. He recently switched his academy from a mix of gi and no-gi training to only no-gi for adults. We discuss how he feels the culture of no-gi jiu-jitsu is progressing and John Danaher's influence on the sport and himself. We also discuss how he views the impact of external vs internal effects on the grappling culture.
