Why do some people stick to running while others prefer cycling, swimming or gym classes? A new study from University College London (UCL) suggests that personality type may play a decisive role in shaping exercise preferences – and in helping people maintain a fitness routine long-term.
The research, led by Professor Flaminia Ronca of UCL’s Exercise Neuroscience Research Group, examined 132 participants including police, healthcare workers and university students. They completed a baseline fitness test, a widely used “Big Five” personality questionnaire and a stress scale. Half were then given an eight-week personalised fitness plan of cycling sessions at varying intensities plus one day of body-weight strength training.
After each workout, participants rated their enjoyment. At the end of the trial they repeated the fitness and stress tests.
Results confirmed known trends: extroverts tended to be fitter, enjoyed high-intensity group sessions and were more likely to join sports clubs, while conscientious individuals consistently scored higher across all strength and endurance tests. Introverts and those high in neuroticism – prone to anxiety – preferred quieter, more independent routines.
Importantly, neurotic participants showed the greatest reduction in stress after the programme, despite being less likely to monitor their heart rate or seek feedback. “They did the exercises – they just wanted to be left alone while doing them,” Ronca noted.
The findings suggest tailoring exercise programmes to personality could boost adherence and health benefits. “What matters most is that we move more by doing something we enjoy,” Ronca said.
Fitness professionals echo the message. Trainers at Hong Kong’s Raw Personal Training said matching routines to clients’ personalities increases consistency and turns workouts from a chore into something rewarding. “Enjoying a range of activities is a powerful reminder that fitness is not one-size-fits-all,” said general manager and trainer Kushal Gurung.
Ronca’s team plans further research to refine personality-based recommendations. For now, the takeaway is simple: extroverts may thrive on high-intensity, social workouts, while introverts may do best with solo routines at their own pace.
