I don't think I ever gave gymnastics half a thought before my daughter made the team. When my girls were pre-school aged they went weekly to the Tumblebus (an old school-bus that has been gutted and outfitted with mats, climbing stuff, etc. and goes to various locations... preschools, neighborhoods, etc.). I was always such a dork physically... I was just excited when they could make it across the monkey bars and do a cartwheel (somehow, growing up, those two skills seemed to mark the boundary between the cool girls and... well... me).
Kathy doesn't even get the best grades in gym class. I think that the elementary gym teacher's main focus is on activities that involve throwing, hitting, and/or kicking a ball and I'm not sure how much gymnastics prepares you for that, other than some basic strength and coordination. Actually, she's a bit of a klutz (with little to no interest in throwing, hitting, or kicking a ball).
