By U.S. Army Master Sgt. Montgomery Miller ASG-QA, Installation Master Fitness InstructorDOHA, Qatar - One of the main reasons why most people fail to achieve what they set out to do is they don't set goals, don't have a plan, or lack consistency which leads to lack of execution.I have numerous individuals from soldiers to civilians tell me what they want, but don't know how to get there or how to plan their workout around there day. Don't you think it should be the other way around? If most people plan their workout around their day, they will never attempt to workout because at the end of the day, they will lack the motivation to finish.In my many years of training people, I notice the one thing that remains consistent is the people that lack a goal will never achieve weight loss or their fitness goal. It is so much easier if you have a goal, because if you know what you want, all you have to do is figure out how to get there and that is what a personal trainer is for. Everyone needs a trainer, because that trainer can correct your form and reinforce proper technique which will help you achieve your goal a lot quicker.Now that you have your goal, it is time to write down how you plan to achieve your goal. I know this sounds too easy but it really is. If your goal is to lose weight, track your progress weekly by weighing yourself and tracking your body fat progress. If you are not losing weight it is because of three reasons: something is wrong with your eating habits, your workout is not hard enough, or a combination of both. Also, if you are not losing weight, but losing inches, you have had a successful week. Just because you don't lose weight, doesn't mean what you are doing isn't working.Lastly, what is the point in having a goal and a plan, if you are not consistent in your workout and diet plan? Too many people have so many excuses on why they never work out or fall off their diet plan. If this is what you really want to do, then you have to make a sacrifice to do it! Having a great attitude towards working out will help improve your execution which in turn will help you achieve your fitness goal. Good luck and let's go workout!<i>Editor's Note: The information in this article represent Master Sgt. Miller's experience as a fitness instructor. Individual results can vary.
