On July 13, 2019 I was invited at Natsugeiko held in Massa (Toscana), organized by Sensei Paolo Ornaghi and Sensei Stefano Martinalli, to teach Okinawa karate. A 3 hours morning lesson in which I paid particular attention to Iri-kumi (sparring) techniques, conditioning and body strengthening. A lot of people took part at this short seminar, and I grateful to above Sensei organizers for that. Thank you also at Sensei Massimo Serrao and his students for participating. Furthermore, in the afternoon, I also taught a private Eskrima lesson to Serrao Sensei.
