Kostya Zhyvanov arrives without knowing which problems BORETS LAB has prepared. The first card puts the 74 kg Sambo fighter into a freestyle-wrestling round with Stas, a 90 kg BJJ brown belt. Zhyvanov reports that the size difference made the match difficult, but that he still won the opening test.

The following cards move across grappling contexts instead of repeating one ruleset: escape Anton Bereda's buggy choke, work from turtle against Anton, and find a submission from standing against 87 kg BJJ blue belt Matvii. The compact format shows how the BORETS system asks an athlete to switch between wrestling, BJJ, and submission-grappling decisions under pressure.

What to watch for

  • The athlete receives four surprise tasks with no dedicated preparation time between them.
  • Zhyvanov reports winning the opening freestyle-wrestling round against a much heavier opponent.
  • The remaining tests cover buggy-choke defense, turtle work, and a submission from standing.
  • Each card demands a different tactical response from the same cross-trained athlete.
