But people aren't changing. I can attest to that. In my 20-some years of being involved personally and professionally in fitness, I have heard unlimited reasons for not exercising.
Some people openly admit they dislike exercise and avoid it with a passion.
I want to do it, but I don't have time. Research has shown that most people who exercise regularly are very busy, perhaps even more so than the non-active exercisers. What I hear when people complain about lack of time is that exercising is not a priority. If you want time, you must make it. Take a closer look at your usage of time.
