DON'T OVERDO IT
A good reminder--I know many of you out there work out and exercise regularly.  But as Dr. Sanjay Gupta reminds, too much of a good thing can be bad for you:
"Q: I can’t stop working out! Is it possible to overdo it?
A: Actually, yes. Let your body be the judge. If you suffer from pain, muscle soreness that doesn’t go away in a day, or loss of strength, speed, or endurance - all signs of overtraining - then you probably need a break from the gym to recover.
There’s also a psychological disorder called "exercise bulimia," or compulsive exercise, in which people work out excessively, often for hours at a time. They get so obsessed with sweating off unwanted calories that it negatively impacts other parts of their life, from their career to their relationships.
If that’s you, try talking to a therapist who specializes in eating disorders."

AND FOR THOSE NOT OVERDOING IT, HERE'S A TIP
To burn a little excess fat, real quick?  Squeeze in some jumping jacks:
"Complement your cardio (30 minutes of walking a day, remember!) by adding in 3 sets of 100 “jacks” throughout the day.
It only takes 2 minutes to complete each set, and you’ll burn a total of 60 additional calories a day. Every little bit helps! Squeeze in a set -- traditional high-impact JJs, or modified low-impact JJs -- before showering, while your computer is booting up, during a TV commercial break, or while dinner is cooking. Such an easy way to get your heart pumping and rev your metabolism!"

one step beyond their greatest failure." -Napoleon Hill
