Exercise is necessary for everyone, whether we like it or not. Wayne and I are finally getting back to working out, we know that we are the example that the girls turn to the most.
The girls are very active and spend as much time as possible outside. I think they could easily live in a tree house so long as it had a microwave and flavored water. They love to go for walks, ride their bikes, pull weeds and chase bugs. They spent 2 hours outside this morning learning to use their kiddo-sized racquets to play badminton. They have recess every day at school for 40 minutes, sometimes they're outside, sometimes they're in the gym. The teachers run with them and make sure that everyone is active. We will be starting swim lessons in a few weeks and Little G has just announced she wants to start taking dance lessons. Ms.J has talked off and on about playing soccer, maybe we'll sign up in the fall.
We always check before, during (about 30 minutes in), and after. The girls react differently to exercise, one is high right afterwards, then crashes 2 hours later while the other one will be lower but rebounds 1 hour later with considerable highs. We always make sure they have lots of water and ALWAYS plenty of sunscreen.
