Jenna Rangel, right, shows off some self-defense moves against instructor Johnny Wiginton on Dec. 15 at Ultimate Martial Arts in Newton. Jenna and her father Chris Rangel have developed a self-defense DVD that teaches teenagers and young women how to defend themselves in potentially dangerous and vulnerable situations.

NEWTON ? As she rushes out into the dark parking lot after shopping at the mall, a text message arrives on her cell phone.

Distracted, the young girl becomes oblivious to her surroundings as she replies.

That’s when teens and young women can be most vulnerable to an attack, said Chris Rangel, who operates Ultimate Martial Arts, at the Chisholm Trail Factory Outlet Mall in Newton.

While he’s concerned for everyone’s safety, paramount is the welfare of his 15-year-old daughter Jenna.

Together, he and Jenna, a Newton High School freshman, have produced a DVD that offers ways for women and girls to protect themselves. It doesn’t take a black belt in martial arts to know some simple safety tips, Rangel advises.

The DVD, “Girl2Girl,” suggests scanning surroundings, being aware, throwing a few blows fast and furious when attacked, and even smashing some feet before escaping quickly to safety and immediately reporting the incident.

Like any devoted dad, Chris Rangel wants to keep his daughter safe. With the lessons in self-defense, she is better prepared for those times she could be in danger and he isn’t there to protect her.

As a sixth-degree black belt, Rangel is confident the lessons he taught his daughter, which she demonstrates on the DVD, will protect Jenna and other females in the case of an attack.

Jenna, the fourth generation in her family to earn a black belt, got on board helping with the DVD after a scary encounter at a restaurant.

She had gone there with friends and family, and was leaving when a 300-pound drunken man started making advances. “He was coming towards me saying ‘Hey, baby’ and other inappropriate things, and I was cornered,” Jenna said.

Her father came up behind her and his presence de-escalated the situation, but Jenna was already preparing to defend herself. She knew the basic moves — use the knee, strike with the palm and smash the foot, hard.

Rangel said females between ages 9 and 24 face attack in the United States every day.

According to the American Association of University Women, 83 percent of middle and high school girls nationally experience sexual harassment in school, with more than half being physical harassment.

On a recent afternoon Jenna practiced several moves on 19-year-old Johnny Wiginton, chief instructor at the Wichita branch of Ultimate Martial Arts. He wore protective police gear as he came up behind her and grabbed her by the throat. Jenna swung around swiftly, slammed her foot into his chest and then stomped his foot.

“We keep it simple,” Rangel said as he watched Jenna practice. But effective.
