mine dont do any atm (for obvious reasons) but am wanting them to start swimming lessons once dh is better and we can take them as i feel its an important life skill, plus its fun and keeps you healthy. my kids are vwery active (would rather run/scooter to school than use the car), play outside for 3+hours after school(only coming in to eat and watch 30mins of lazy town), love walks round the lakes etc etc.
