Regular exercise is associated to several health benefits. However, only 39% of adults with type 2 diabetes reach the recommended goals for physical activity. Adherence to exercise needs removing barriers to behavioural changes by setting realistic goals. To make the change lasting, group is fundamental and automatic behaviours must be created. However, the extent of the problem clearly indicates that a patientcentred approach is not enough. National policies including programs to encourage regular exercise are needed, with intensive interventions and investments.
