Diet Motivation Success Strategy #2:

TRANSFORM YOUR FITNESS GOALS BY SETTING SMART GOALS

Goals come from having a clear vision of what you want. Knowing that you want to build your very best body is a great start, but you need something more than that—a statement so compelling it literally pulls you, like a magnet, in the direction of its achievement.

So you say you're not certain how to set effective goals? Well, don't worry, everyone starts off this way...merely stating they want to get into better shape or have a slimmer waist. And these statements might be as good as it gets for them.

But to really set effective transformation goals and ensure you'll reach them, you're going to have to learn what I call the SMART technique in goal setting to pave your way to sure success.
Using the S.M.A.R.T. technique will ensure you've set an effective and commanding goal and compel you to achieve it. Not only will this technique enable you to set the most effective commanding goals, it will help focus your efforts on exactly what you want to achieve.

S.M.A.R.T. stands for:
(S)pecific—you must be specific about what you want to achieve, creating your goal in the present tense…that means using "I am (in the process of…)" to start your goal statement.

(M)easurable—how do you measure "better shape" or a "slimmer waist?" You can't. Therefore, you must ensure your progress can be measured by scaling your goal to a specific number (e.g., 10% bodyfat, a 33-inch waist, or a size 6).

(A)ction-oriented—you must be able to create an action list of things you must do to achieve success (this is similar to a to-do list, only it pertains directly to the achievement of your goal).

(R)ealistic—make certain your goal is realistic, that it stretches you but is something you can achieve, given your expectations and timeframe.

(T)ime-conscience—this is where we harness the power of a deadline. Nothing becomes important to us unless we set a deadline on it.A date forces us to give it priority and set positive pressure on us to achieve it.
