This may surprise you, but only one in five teenage girls exercises consistently. That's according to the U.S. Department of Health. So today, Salt Lake teens started a pilot program to get them moving. News Specialist Nadine Wimmer reports.

It's pull-up day for the fitness test in girl's gym class at Bryant Middle School in Salt Lake. They try, and try to pull their chins to the bar.

Student: "I CAN'T DO IT."

Nadine Wimmer, Eyewitness News: "THE GYM TEACHER HAS WRITTEN A GOAL ON THE BOARD OF TWO PULLUPS FOR EACH GIRL. THAT WOULD BE THE IDEAL FITNESS LEVEL, BUT MOST GIRLS COULDN'T EVEN DO ONE."

Educators have found this is the age group, young teens, where many girls lose interest in exercise.

Megan Bennett, Student: "PROBABLY ABOUT ONCE A MONTH WITH MY DAD OUT IN OUR GARAGE."

Cappi Stanper/Student: "THEY PROBABLY THINK THAT THEY'RE EMBARRASSED, OR THAT THEY WON'T DO AS WELL, BUT BOYS JUST GO FOR IT."

Brittany Rupp/Student: "SOME OF THEM LIKE TO DRESS UP AND STUFF."

"YOU GET ALL SORE AND STUFF."

It's a serious trend, since habits developed now, will likely follow them in life.

Kaye Wilde/Gym Teacher: "REAL PROBLEM THAT'S BEING RECOGNIZED MORE AND MORE. THIS AGE GROUP, AND GIRLS ESPECIALLY, THEY'RE NOT AS ACTIVITY ORIENTED."

So the Utah Starzz, and the University of Utah have begun an effort to get these teens to move.

Tammi Reiss/Utah Starzz: "WE MEAN JUST BODY MOVEMENT, GETTING YOUR BODY MOVING, GETTING YOUR HEART RATE UP."
