A study that followed people to see how long they stuck with their New Year's fitness resolutions has found underlying motivation was a significant factor when it came to adhering to goals.
Edith Cowan University professor of psychology Joanne Dickson, who was the lead researcher on the study, said it also found tenacity and the ability to adapt in the face of difficulties weren't big factors in whether or not people stuck to their goals.
"We thought those two motivational mechanisms would actually help people stick to their resolutions, but it wasn't the case," Professor Dickson told Ivo da Silva on ABC Radio Perth.
