Step out of your comfort zone.

This isn't a personal statement, but your body is lazy. As a survival mechanism, in effort to conserve energy, your body is always looking for ways to make things easier.   This is the process of adaptation.  

When you systematically and progressively lift weights, you get stronger.   When you challenge your muscle's extensibility by stretching, you become more flexible.   Stimulate and adapt.   It's a simple concept, really.   Nietzsche understood it in the 1800's ("that which does not kill you makes you stronger").   Now what about the other side of the coin?  

If your job/lifestyle involves little activity, such as sitting in a car, at a computer, or in front of the TV, your body will also adapt to that.   Muscles will weaken.   Your ability to do anything requiring more than pressing the buttons on a keyboard or remote control will diminish.   With stimulation that causes adaptations such as these, your overall health & sense of well-being suffers.

If you want to avoid these negative adaptations, you have to challenge yourself.   Not going full bore right out of the starting gate, but to achieve maximum benefits from a fitness program, you have to train slightly beyond what you perceive as comfortable.   Otherwise your body has no reason to adapt.   A little discomfort (but NOT pain!) in the short term results in a much healthier, physically fit body in the long run.   Be safe, but make yourself "uncomfortable" for at least 30 minutes each day.   Your body will thank you for it.

If you're not sure how to safely push your body past your comfort threshold, Absolute Fitness can show you the way.
