My initial trigger....
to feel fitter, be able to run with the dog and kids.
but also because I knew that I was going to die before my time, and that I owed it to my wife and kids to do something about it.
However, more than anything else - it was for ME! Years of low self-esteem, feelings of unattractiveness, poor health. Something just clicked and I took control.
Since I lost 'weight', I haven't stopped - I want more and more fitness. Despite back pain and running injuries, I refuse to give up (although I sometimes take a tactical retreat) - I go to gym 2 to 4 times per week, I go running about once per week, and I love eating healthy! I do it for me first - then my family.
