This article offers results of research on fitness motivation. The first part is focused on primary, the second part on secondary motivation. The experimental group was created by fitness clients (50 persons in the first part, 100 persons in the second part). We used verbal questionnaire that we created ourselves. Primary motivation: the main motive was losing weight by woman, losing or puting on weight by men. Health and conditional motives are more important for men too. Secondary motivation: for the most of respondents is still the most important motiv changing their body (losing weight, puting on weight, body shaping). For 20% of them is the most important motiv “to work on myself, get better”. Psychological motives (I have better mood after exercise, need of exercise) are more important for this group.
