A bit cold and dark out our way for me @zoffiel hence the treadmill. Travelling for work, etc can take a huge chunk of time - for me it's a minimum of 400kms per week without adding on any extra trips for the kids.
I guess my point is, work out what you are happy doing with regard to exercise - swimming, weights, bikes, running, walking. Try to assess the best way to go about it that is not going to leave you so tired and stressed that it makes you feel worse. Then work out what the obstacles to achieving it are going to be and try to come up with solutions. If you can get rid of the demotivators, you're more than halfway there.
