Preventing illness !
Are you feeling tired and exhausted ? – Having frequent colds ? Well, I can tell you that research indicates that exercise builds up and improves circulation of our white blood cells, which we need to fend off harmful bacteria that cause us to get sick. This helps to prevent us from getting sick. However, after we become ill, our improved circulation due to regular exercise can help us become well again.
My personal experience is that this works for me,- but what about major illness ?
Preventing disease ? – yes, similar research indicates that physical activity and exercise provide health benefits which positively effect a wide range of factors contributing to the quality of life, there are a few overarching areas of disease or health complications where regular exercise predominately reduces risk or aids in controlling disease.

6. Autoimmune disease – Rheumatoid arthritis
It´s never to late – so long as the type of physical activity engaged in is appropriate to one’s physical ability. Start out slowly and safely and build up to the recommended frequency, duration, and time.
