The key objective of our research is to look into the fitness sector and explore how Myers-Briggs personality types influence the training session attendance-related habits and main motivational factors of fitness consumers. These key driving factors are motivating the fitness sector consumers to attend training session and determine the physical activity of sportspeople. According to the Myers-Briggs Temperament Index, extraverted – sensing – thinking – judging type proved to be the most common within the sample. Based on our results, the period and regularity of training sessions does not depend on the personality of fitness consumers. However, based on their main motivations, significant differences have emerged in different preference dichotomies. We can assume that fitness gym trainings are mostly popular among sportspeople with extraverted – sensing – thinking – judging personality type, so it is worthwhile for fitness providers to consider the motivation and aims of their target group.
