Two other people in the swimming area were not injured, police said.
“It definitely could have been a lot worse,” Centerville police Sgt. Jeff Kaercher said.
Jim Lee of Xenia was at the fitness center when he saw all the commotion.
“I was just working out and then I saw a bunch of people running toward the locker room,” Lee said. “I walked out and there’s a car in the pool.”
Lee said he was thankful more people were not in the pool area, because he has seen as many as 30 to 40 people in the pool during water aerobics classes.
