Differences in self-motivation factors between the women and men: Women were more likely than men to be motivated to exercise if they had an instructor to guide them (blue cells: 20.5% vs 1.96%, adjusted p = 0.027), whereas men were more likely to participate if they were able to control the type and difficulty of the exercise (green cells: 82.4% vs 57.7%, adjusted p = 0.001).
