Fibromyalgia affects 2 to 5% of adults in the general population. Patients describe a combination of symptoms centred around fatigue not induced by exercise and not relieved by rest.

The diagnosis of fibromyalgia is self-perpetuating by the deconditioning, consequence of a reduced muscle mass due to inactivity and periods of prolonged rest.

Thus, it seems fundamental to develop other non-drug approaches: among them, adapted physical activity is recommended by most learned societies because of a good level of evidence (Level 1, Grade A). The question remains, however, whether simple advice to resume physical activity is sufficient (routine care with medical assessment at 3 months) or whether a physical activity supervised inside and outside the hospital is not more relevant.

Inclusion Criteria:

• Patient lived in t Loire (42) or Haute-Loire (43)

• French writing and speaking
• Sedentary or low level of activity (less than 2 hours of regular physical activity per week at the time of inclusion)
• Signature of informed consent

Exclusion Criteria:

• Cardiac or respiratory diseases that contraindicate the practice of physical activity
• Significant co-morbidities that contraindicate the practice of physical activity: associated cardiac pathologies (severe rhythm disorders such as rapid atrial fibrillation), respiratory pathologies (severe obstructive or severe respiratory insufficiency), disabling joint pathologies (knee osteoarthritis or osteoarthritis of the hip) training on a treadmill or on a high intensity bike).
• Impossibility of submitting to the medical monitoring of the program for geographical, social or psychological reason
