Polish striking savant Martyna Dominczak knew that unlocking her true potential would require leaving her comfort zone.The 23-year-old started her ONE Championship career at strawweight with mixed results.Dominczak dominated Nat ‘Wondergirl’ Jaroonsak via TKO, but stumbled in a closely-contested unanimous decision loss to Ekatarina Vandaryeva.The Legion Glogow representative figured it was time for a change, and she made the move down to 115 pounds.Dominczak’s deadly speed was enhanced at the lower weight class, while her strikes still carried impact and precision in her impressive win over Yu Yau Pui.The Polish hammer looked even better in her second atomweight fight, having her way against Cynthia Flores last June.Speaking to ONE Championship, Dominczak reflected on her growth since moving to a new division:"I think I'm a totally different fighter right now [from my first fight last year] because this will be my fifth fight in ONE Championship. Now I know all the rules. Now I know how to punch with the small gloves, how to protect [myself] with them.”She continued:“Also I'm in a smaller weight category. My body is feeling better here. It's my first time doing this weight, so I know how my body will react. And I'm more experienced."
