My little guys do swimming twice a week which is not only a good way for them to burn off energy but an important life skill. It only costs me $48 for four lessons (Ds3 is once a week and free because Im staff) which is reasonably priced. I know it ends up being less again for 3 lessons a week. Maybe enquire with your local swim schools?

We're looking at buying bikes for us all soon so we can all go bike riding. Is that something you could do?

Ive been contemplating karate or soccer or something for Ds1 (he is 4.5). I know there are a few lowish cost things for kids to do as far as sports go, do you have a local YMCA? I know they do all sorts of classes for kids!
