Youth MMA Foundation: Swimming and Wrestling
Okniński argues that early specialization in striking or MMA is a mistake. He uses his son Aleksander as a case study: despite being very tall (a disadvantage in wrestling), he trained wrestling and became a Warsaw champion as a child. This base allowed him to walk on his hands across the gym at age 25 and perform backflips. The swimming base gave him the cardio to spar for 30 minutes continuously. Okniński believes this combination creates a durable, well-rounded athlete who can later add striking skills onto a perfect physical foundation.
Swimming develops lung capacity and a lean, symmetrical musculature without impact. Wrestling develops proprioception, balance, and the ability to control one's body in three-dimensional space, which is foundational for all grappling and clinch work.
My son... trained wrestling and, damn, it bothered him a lot because tall guys have a hard time in wrestling, but he trained wrestling not to be a champion... he trained that wrestling and he trained swimming, all through school he swam and trained wrestling.
If someone wants to be good at MMA, I would send them to swimming and wrestling.
