The last thing you want to do at the end of a workout is stretch. You know that stretching the muscles is the only way to remain injury free. You know that nothing refreshes you as much as a good stretch. And yet, when you are pushed for time, you prefer to skip the stretching, instead of sacrificing a few minutes of the workout to do it. Perhaps it is because the act of stretching itself can be painful at times.
Whatever the reason, change the habit, and s-t-r-e-t-c-h.
And do all those other things that are good for you.---------
