i admit that i do very little excercise
In the main, I'm pretty active, but when I was working on losing weight, I used to do things like deliberately not buy enough milk (for example) to last until my next usual shop, so that I would have to get out and buy some. I'd then ensure I walked or get on my bike to the nearest shop, rather than drive to the supermarket.
I know shopping in the corner shop can be expensive, but the odd carton of milk didn't feel too catastrophic.
Similarly, because in the tropics rubbish is not collected from each house; it's picked up from a central collection point, only a couple of hundred yards away, I'd take our rubbish each evening, once my OH had started cooking dinner. It only took 10 minutes or so, but all helped. In the end, if i didn't go I'd miss it; meeting all the other exercisers out doing their thing.
(The rubbish, although not collected from the doorstep, it is collected several times a day because of the heat.)
