Building Energy Reviving exercise

If you are feeling sluggish in the afternoons or after work, try a little reviving exercise by taking a swift walk or jog around the block. Expending energy in exercise helps maintain energy levels because it expands the ability of the heart to pump oxygenated blood around the body.This in turn increases your ability to process and use oxygen, an ability which declines with age, even if you are otherwise fit and healthy.
