Rutherford didn't think too much about it. He may be a track runner, but he'd occasionally practiced boxing before too.
Of course, he didn't train to go compete. It was for the coordination of his arms. The movement of arms was especially important for sprinters.
In fact, running with a different posture might bring a 0.1 second difference.
Rutherford looked at how David punched and chuckled. His move was really improper, but the sandbag broke the moment he punched it. Sand shot out of the other side.
Rutherford gaped at David in shock. "Amazing."
"I'm sorry, I broke your sandbag," David said apologetically.
"It—it's okay… Are you a professional fighter?"
"No, I'm a police officer."
"Have you participated in the FDD before?"
