Motivation, it's a tricky thing. The key to getting and staying motivated is for you, the individual, to understand what motivates you and why. Then, hopefully, you will be able to gauge your motivation and thereby stick with your exercise program through all the ups and downs and twists and turns that accompany a new or different regimen and how it coincides with the typical busy lifestyle. Take a look at yourself and the reasons why you work out, and figure out what you could do to increase those motivations. Think of it as levels -- or stages, if you will, that gauge how important exercise is and the external or internal motivators that are attached to said levels. Motivation ranges anywhere from a complete lack all the way to an unspoken and often unrealized need to exercise. Absent motivation is where there are zero factors that would cause one to engage in some form of activity, and subsequently there is none. The next level of motivation would be where the subject is completely obligated to become involved in some form of exercise because of outside influences, such as wanting to be accepted more by peers or liked better by the opposite sex. Beyond that, people are typically motivated by shame, (i.e. they would look upon themselves in a negative way if they didn't work out) which can be seen as the beginning of positive internal motivation, but this form yields small results as the respondent is not exercising to achieve specific goals. If an individual believes exercise to be important, this is the level where many, who work out, on a near daily basis, get motivation. This behavior can subsist for a long time and typically is progressive in such a way that the person sees many goals achieved and progression sustained. Finally, those who hang in the aforementioned level of motivation for long enough, eventually see exercise as a part of their lifestyle, something they do because they receive a sense of deep seeded pleasure and enjoyment in doing. This is where all of us, who exercise should strive to be.
