Exercise as a practice versus something you "just do" presents far more opportunity for your enjoyment, benefit and overall health.
Just showing up might be a start. It forms the habit if making time for a new thing; exercise in this case.
The practice of exercise is a commitment as opposed to a trial or something more akin to child-like play.
For most people, this need not and should be extreme. Merely showing up is enough.
Merely showing up (thank you, Seth Godin) for your regular exercise practice and deliberately making it a part of your day-to-day being is what sows the seeds of the fabulous outcomes in feel, function and look that so many of us desire.
