An example of what happens, we get all excited and set ourselves up, however we need to be realistic so not to fail...
Set out to just “be healthy” and you’re selling yourself short. Vague goals give people too much leeway and can lower their motivation to push themselves.
So be precise and say, for example, that you want to lower your body fat by 5 percent or be able to run a 10-K.
You should be able to gauge and quantify your progress, both in the short-term and long-term. Set micro (weekly) and macro (monthly) goals to keep yourself on track.
Be Attainable If you can barely find 20 free minutes in your day, don’t set yourself up for failure by saying you’ll run for 50 minutes five days a week.
Be Realistic Even with the smartest plan and the strongest determination, your body can only handle so much. Sure, fast weight loss is possible, but if you drop more than about a pound and a half a week, you’re most likely looking at muscle and water loss—not fat.
Be Time-sensitive Deadlines create a sense of urgency and make your goal a priority. Give yourself a year to drop 75 to 100 pounds, four to six months to train for a marathon (if you’re a new runner), and two months to lose 10 percent to 12 percent of your body fat.
