But with taekwondo, the children can focus their energy positively.
"We've found an exercise routine which can change children. Maybe even more than schools, because they actually enjoy it," says Rashid.
Taekwondo "is teaching us good manners, while making us stronger" said Ibrahim al-Hamidi, a 13-year-old Syrian refugee participating in the training.
"It's good for our bodies and muscles and it teaches how to defend ourselves," he said.
As of now, only boys learn taekwondo, but the AP reports that girls will be included at a later stage.
Coach Rashid said he already sees a positive effect. "In one month, their bodies have changed a lot. And they are also more in control of their minds."
"Taekwondo is amazing," said student Ali Badran, 13, from Daraa. "Once I go back to Syria, I want to start teaching Syrian students."
