SUMA Clubs Joint Training in Polevskoy: SK «Tandem» and SC «Tetris»

On December 14, 2025, a joint training session and friendly matches were held in Polevskoy among clubs of the SUMA International (ISUMA) network. SK «Tandem» (Polevskoy, official SUMA representative) hosted the event under coach Nikolai Viktorovich Sofronov. Guests came from SC «Tetris» (Saint Petersburg), led by coach Vladimir Leonidovich Glushchenko. Friendly bouts were held in jiu-jitsu and KUBO (Classical Universal Wrestling). Athletes showed excellent preparation: exciting matches on the mats, experience exchange in sparring, and off the mats — new friendships and warm communication among athletes and coaches. Such meetings strengthen ties between SUMA clubs in different cities and help develop martial arts through mutual respect and cooperation. We thank all participants for their productive work!
