After a series of assaults in Brooklyn over the last few months, women in all five boroughs are feeling threatened.

But rather than stay off the streets and subways, many are learning to fight back, and maybe discovering a new martial arts-based fitness routine in the process.

“Our phone has been ringing off the hook,” says Tracy Hobson, executive director of the Center for Anti-Violence Education in Park Slope. “Interest has more than doubled.”

While some come for just one class, Hobson says the majority of the women regularly practicing martial arts at the center originally came for a self-defense seminar, and stayed because of the physical and internal strength the practice created for them.

Eve Gold, the co-owner of Krav Maga NYC and director of the Krav Maga Federation, said that women’s interest in Krav Maga always peaks when attacks occur. And out of ten women who took a recent introductory self-defense class, seven signed up for continuing classes.

“Self-defense is a practical measure you can take to make your life a little bit safer and to feel a little bit more confident,” says Amy McPherson, a graduate student who recently took a free class at CrossFit 718 in Park Slope. “And getting a little taste of the method made me think I would really enjoy it as a workout.”

It also works the other way around. At Fitness Fight Camp, a Muay Thai boxing-based workout program, the focus is on calorie burning. But women learn techniques to defend themselves by default.

“Once women realize how hard they can hit or kick or knee, and how great they feel doing it, it makes them feel bad-ass and strong and empowered,” says Laurel Holloway, co-founder of Fitness Fight Camp. “Realizing their own strength makes them feel more confident about walking home at night.”—Lisa Elaine Held
