If you have not been able to meet your gym goals despite persistent efforts to wake up early or hitting that running session on a hot summer afternoon, blame it on your personality.

According to researchers from University of Oregon, some people seem to be able to more consistently meet their goals than others, but it remained unclear if personality traits encourage individuals to achieve long-term goals in their day-to-day lives.

Conscientiousness has long been tied with healthy behaviours.

Narrowing their focus to "planfulness" — lead researcher Rita M. Ludwig and colleagues Sanjay Srivastava and Elliot T. Berkman, they zeroed in on psychological processes -- such as mental flexibility, and a person's ability to make short-term sacrifices in pursuit of future success that contribute directly to achieving long-term goals.

"There indeed appears to be a certain way of thinking about goals that correlates with long-term progress," said Ludwig.

"What's new in this study is that we used an objective measure of goal progress that could be recorded as participants naturally went about their lives: their check-ins at a local gym".

The team analysed gym attendance of 282 participants over a 20-week period.

While all participants experienced a similar decline in gym attendance over the course of each semester, individuals who rated themselves high on "planfulness" items such as "developing a clear plan when I have a goal is important to me" went to the gym more throughout both semesters compared to those who ranked themselves lower on "planfulness".

"Planfulness" was only significantly associated with the frequency of participants' gym attendance during the winter semester, possibly due to participants completing their physical activity plan later in the year, the researchers noted.

"It seems logical that people who are successful with their goals would be able to write in detail about their planning process," said Ludwig.

"We were surprised, then, to find no relationship between people's goal pursuit behaviour and how they wrote about their goals."
