When is the best time.?

A New York Times article discusses the optimal time for exercise for weight loss.  The short answer is immediately upon waking, before breakfast.  

However, there's more.  There always is. Weight loss is only one reason for exercise.  You might exercise:-

•  To clear your head
•  To change your outlook- cheer yourself up 
•  To strenthen muscles in order to have more fun
•  To strengthen oarticular muscles for an activity, say sport, improve your swing
• Bone density increase
• Reduce the risk of falls
• Improve your memory and cognitive function.  More about this later.
• To keep well, Prevent disease
• To ease your pain or symptoms
• To slow the ageing process
• To become more flexible - mentally and physically. "Yes you can"
• To sleep better
• To have fun

So you can see from this hastily put-together list that there are many reasons for undertaking exercise.  Sure, an early exercise session might be the best for weight loss. However, it is not the only reason to exercise, and we must all read helpful articles very carefully.
