Not sure why they expect a 10 year old to break concrete. It's not even worth trying, it's a completely pointless ability and your daughter can easily injure her hand smashing against a brick. Unless the goal is for her to be a sport/tournament fighter, but I assume the intent is to learn actual life-relevant self-defense abilities.
