Stress...it gets the better of all of us at one time or another.  Those times when you feel so overloaded where you just can't think straight.  Before that stress level gets the better of you, make some good use of all that adrenneline and work off that stress in high intensity workout!  It's too easy to talk yourself out of your workout. So, instead of using the excuse that your too stressed, use it as the reason you should go to the gym. Releasing those endorphins will make you feel so much more in control.  You may not have everything figured out but it will definitely help you move forward.
