I liked it... and your kids are going to be badasses if they continue their training throughout... no worries about your daughter going on a prom-date... well yeah there ARE "other" worries for a parent but... her date should be careful. As for your boy... well he'll probably go through life saying "what bully?? where?"
Your editing is good... didn't distract too much from the workouts, bit long on some, but still watchable.
