Education is not the problem. People know sugar is bad, people know cigarettes are bad, people know alcohol is bad, still millions use these substances every day.

What works best is to find some form of exercise that you really enjoy. I will get up at 5 in the morning, skip diner, skip appointments when i get a change to exercise, just because i enjoy it so much.

In addition, what also helps is to ensure normal activities require excercise. I will walk to the shop every day for groceries, walk the dog every day, cycle into town, best if you can cycle to work.
