My first question would be, how do children travel to school/other activities?
Children need more than 60min of physical activity a day. If you don't have a built environment where walking/cycling to school or just playing outside isn't a viable option, that is hard to accomplish. Even in PE classes and sports clubs the amount of real activity is much less than what the allocated hours would suggest as much time is used in instruction and other things.
Second question: How long are the recesses between classes in school and what do children do during them?
Is playing or doing sports with friends possible within short proximity of the home, where children can go independently?
If you have the right environment, the children will get more than enough physical activity every day. Mostly because that's what children do; run around, play and explore their surroundings. And that is one important factor in overall fitness I believe.
