Going more often to power yoga and ashtanga classes. It is easier once school is out and there's no even practice pickups, games, or homework assistance needed in the evenings.
And taking the stairs vs elevator. In the winter, I always have a coat on so it's a PITA. In summer, I travel light so stairs are an easy pick-me-up each day. I climb a few flights past my floor - or to the top - and then go back down another staircase to my floor.
