Karolina Kowalkiewicz apparently put herself through some kind of training for UFC 238.

Kowalkiewicz, former strawweight title challenger, will be looking to snap a two-fight losing streak on Saturday night when she takes on Alexa Grasso on the ESPN-televised prelims at United Center.

To prepare, Kowalkiewicz decided to use only male sparring partners. No women. Why?

“Because guys are stronger and better,” she told MMA Junkie this week.

Kowalkiewicz added, “When I spar with girls, after sparring I was OK. And after sparring with guys, I was like, ‘I cannot breathe. What happened?’ This is big difference for me.”

We’ll find out if it pays off at UFC 238.

Watch the video above to hear Kowalkiewicz (12-4 MMA, 5-4 UFC) break down her matchup with Grasso (10-2 MMA, 2-2 UFC), explain why she had to fight in Chicago, and more.
