Students were running to increase endurance, I was telling my younger students to breathe through their mouths. Inhale and Exhale. One of my students went home and told her Mom I was using a word she didn't think I should be saying. Mom asked, "what is it, what is Coach saying?" Student replied, "well, she is saying in hell and ex hell!" I got that one straight the next day! No more running "in hell" in my classes!
