I can't handle exercise for exercise value..I love the outdoors and nature so cycling , bushwalking , kayaking etc help to keep me fit and as I enjoy them I don't have to force myself to do them.
When I used to live in the burbs I used to cycle to work which was good as then I'd done my exercise and didn't feel guilty if I didn't feel like doing anything when I got home.It depends on how far work is from where you live & how cycle friendly the area is too. Mine was about 12kms all up & over a big hill.
I find the fitter I am the more exercise I want to do..However I've just come back from a weeks XC skiing and I was feeling really fit afterwards but I've lost most of it now..

slack + a lot of wet windless weather.
My fitness ( or lack of it ) really affects my sailing. After the weeks skiing I was holding down the big sail in more wind , sailing better and everything was so much less effort & more fun..
Try & find something that interests you and can fit into your daily life without too much drama & then your more likely to do it.If you like the outdoors join a bushwalking club as most do kayaking , walking , cycling , canyoning, skiing , caving , abseiling etc..only problem is if our club is typical that the demographics are 50 years old +
