Should I work on a daily exercise plan or a weekly exercise plan? I just realize that that is what I need to do. I have lately been thrown off. Maybe a daily plan would work considering I have actually done some exercise. Should I also list on the benefits of any exercise I have done? I didn't exercise today and now I have felt the effects of the lack of exercise like depression and tiredness. Exercise and diet matter and now I know that hindsight is 20/20.
