I'm a certified children schildrens aerobics instructor, but I also have a background in part time dance and gym teaching.
The other day I was coaching my 8 year old-year-old daughter and her two teammates in her three girl-girl group. I got the girls to start off doing stretches and warm-ups when one of them let out a fart which made them all start to laugh, getting our lesson side trackedsidetracked. Later on when we were in the middle of the routine I could smell a really stinky smell and concluded that one of the girls must have farted again, interrupting the good progress we had made that lesson. I had to stop practice, because they preceded to start arguing over who'd done it.
I kind of gave-up at this point and just sent them all of to the potty for a break because they were getting silly. I had to spray the gym out with air freshener, because it really was starting to smell, and I waited for the girls to come back. We have regular talks about dietary needs at class as well and what to eat before, at and after training days, so I don't know why are these girls are always so gassy?
