Health Education Programme Through Physical Exercise for People With Severe Mental Disorders

The goal of this clinical trial is to \[learn about, test, compare etc.\] in individuals with severe mental disorders and obesity comorbid. The main question\[s\] it aims to answer are: * Are inflammatory activity, oxidative and vascular damage and metabolic mechanisms, as well as neurocognitive and functional performance, related to different physical exercise interventions? * Do inflammatory, oxidative stress and cardiometabolic biomarkers predict neurocognitive improvement after physical activity training? Participants will guided-exercise of moderate intensity and frecuency, and incentive of autonomous physical activity proposals by the specialist; guided physical activity group (GPAG), or (b) 12 weeks of an exercise program standard physical activity without guided and incentives; standard physical activity group (SPAG). If there is a comparison group: Researchers will compare GPAG and SPAG to see if inflammatory, oxidative stress, and cardio-metabolic biomarkers improve neurocognitive performance after physical activity training
