In training, the key to success is consistency.
Sometimes you may find you’re not in the mood, or you’re short of time, or there’s a pressing problem, or your mind is engaged.
All of these things can contribute to either skipping your training entirely or doing it in a haphazard way.
To apply yourself regularly and to make sure you get full benefit from every session you do, is a skill
Learning that skill and applying it will raise the value of every workout you do. What this means is that whether you are short of time, are under pressure, or distracted in some other way from your plan, you will be able to apply yourself to your program, ensure continuity, achieve consistency, and make sure that you get good results.
This is the secret of every successful trainer; consistency. As in everything else in life, you will have good days and you'll have bad days.
But because your practice, application, is consistent, it is physically impossible for your mind, body and attitude to not respond.
This response overspills into everything else. You'll find that as you decide to deal with the matter of consistency in your discipline of training, you'll do the same in your work or any other area.
There's a saying that 'as you do one thing, you do everything.' That means that as you cultivate the habit of training, for 10 minutes or two hours, the mind is inculcated with that attitude, and your training becomes not only a physical workout, but a mental exercise.
Of course there will be days when your performance will not be as wholehearted as it is on other days. But that’s life, isn’t it?
Though there are days when the intensity may not be in the workout, but keep in mind that you're still making progress.
At the end of a three month period, for instance, your mind and body won't know the difference with which you applied yourself on any given day.
What they will know, though, is that the work has been done and that they will have responded accordingly.
Go to it.
