When you set a goal related to your health and fitness, to give yourself the best chance at achieving that goal you need to make it SMMART.
Specific – When creating your goals, make sure you specify the who, what, when, where, why, and how of what you are planning.
Measurable – Avoid setting goals that you can’t quantifiably measure or track.
Motivational – Your goal should motivate you and those around you. If you are not excited about working toward achieving your goal, then perhaps you should rethink your motivations for achieving the goal in the first place. In the health industry sometimes you will find that the goal does not motivate you, but you need to do it to extend your life. If that is the case, use external motivations such as your family and friends to motivate you to achieve your goals.
Attainable – It is good to be ambitious, but do not be so ambitious that your goal becomes impossible to achieve. If you currently can only walk a mile before you are winded, it is not a great idea to say you are going to run a half marathon in 2 months.
Relevant – Ask yourself if your goal is worthwhile and worth your time. While a goal to eliminate gluten from your diet will help if you have a gluten intolerance, eliminating gluten may not be relevant to your overall goal of improving your health.
Time Bound – Set a time frame for when to complete the goal. Will it take a month, a year, a lifetime? It is up to you to decide, but a goal without a deadline will never be achieved.
