A questionnaire made specifically for the case evaluating different domains (length of the sessions, hardness of the sessions, daily repetition of the sessions, difficulty in particular exercises, willingness to repeat in case of re-admission, overall satisfaction to be included in the program) - Likert scale (1 to 5, being 1 not satisfied at all, and 5 highly satisfied).

Evaluation of physical activity using the Get Active Questionnaire for Pregnancy. The questionnaire self-classifies how often and for how long she is engaged in physical activity of a light, moderate or vigorous intensity. Also, it addresses the question whether the woman should speak to her Obstetric Health Care Provider before beginning or continue to be physically active.
