After all, letting Haruno Sakura and the others battle other children, even without using Chakra, just their physical bodies were enough to defeat most of the kids who only knew amateur fighting.
Ah! What a headache!
Taking the students to the playground, Iruka said, "Everyone, warm up first, run around the playground for ten laps."
The school's playground wasn't large, one lap was only four hundred meters, ten laps were four thousand meters.
For Haruno Sakura and the others, it was a piece of cake, but for the other students, it was still a challenge. Many students were gasping for air after finishing.
"Everyone, after running, don't sit down right away, get up and move around, flex your muscles, otherwise your legs and feet will become even more sore and numb." Iruka clapped his hands to draw everyone's attention.
"Next, is the real combat training."
"First group, Naruto Uzumaki VS Haruno Sakura!"
"Starting in five minutes!"
