Gabrielle Czernik didn’t come to BJJ looking for self-defense skills — she came from a background in competitive triathlon and long-distance swimming.

And, well, that background may explain why she’s skeptical of one of the sport’s most common selling points.

Asked by host Alysa Couce whether Jiu-Jitsu genuinely holds up as self-defense, Czernik didn’t offer much reassurance:

I wouldn’t advertise Jiu-Jitsu as a good self-defense.

Czernik started training in December 2018 at Marcelo Garcia’s gym in New York City, after a friend talked her into trying it as a winter activity.

A few competitions later, it became clear the sport was more than a seasonal substitute for outdoor cycling, and she eventually relocated to Pennsylvania to train full-time at Movement Arts, where she earned her black belt and has remained since.

Czernik agreed Jiu-Jitsu builds real physical awareness, but stopped short of calling it dependable protection:

I think body awareness. Before Jiu-Jitsu, if someone had put me in like an armbar, I wouldn’t understand what was going on.
Now, if someone strains my arm, I’m like, don’t do that to me…

I think giving you more awareness of what is dangerous. I think that’s really important.

Beyond that, she doesn’t see the sport’s competitive framework — built around points, guard retention, and positional hierarchy — translating cleanly to a real confrontation.

Czernik tied this back to how the sport shapes movement more broadly, contrasting it with the more linear physical demands of running and cycling.:

In Jiu-Jitsu, you just kind of learn to move in a more 3D way.
