(CNN) -- For four years, I dated a man who beat me.
The first time it happened it was around Christmas of my freshman year of college. I had known him a couple of months. He was the first guy I had ever had a physical relationship with, and I was madly in love.
But he had a dark side, a short fuse, and I was very vocal and told him what I thought. The problem was, instead of arguing with me, he just beat me up.
The episodes continued throughout our relationship. At one point, he actually put me in the hospital with a concussion, my face and body covered with cuts and bruises.
My friends begged me to leave him. His fraternity brothers did an intervention of sorts and told me he was a no-good, nasty SOB. But for some odd reason, which took hours of therapy to figure out years later, I just stayed with him.
It wasn't that I was unpopular or lonely. I had lots of friends, men and women. I was a good student, a leader on campus. I came from a loving home, with a father who never hit my mother, or me. But for years, I had a secret that only the closest of my friends knew about: I was an abused girlfriend.
According to the 2010 National Intimate Partner and Sexual Violence Survey, 32% of women are physically assaulted by a partner during their lifetime. I was one of them.
The question is, why did I stay?
The American Psychiatric Association says that women remain in abusive relationships for many reasons: lack of finances, poor self-esteem, children and even religious and cultural values. In my case, I felt I had done something wrong and deserved it.
(Life by DailyBurn) -- Anyone who makes fitness a priority has experienced that moment when a slight tummy rumble comes along just as you head out to the gym.
But do you grab a snack to get more out of your workout? Or skip the food to avoid stomach cramps and potentially "undo" everything you're about to accomplish?
And if you do choose to fuel, should that be with a protein shake, an energy bar, a handful of nuts or a piece of fruit?
Pre-workout snacks shouldn't make you feel stuffed but it is important to eat up, says Cynthia Sass, a registered dietician. "Exercising on an empty stomach can lead to the breakdown of muscle tissue," cautions Sass.
Without food to fuel your workout, muscle tissue is instead converted into glucose to provide the energy you need, which isn't ideal -- whether you're trying to build muscle or lose weight. This breakdown can negatively impact your metabolism and might even lead to injury.
Food for thought....
What to eat after a workout? Eat well, exercise for longevity
In order fuel up properly pre-workout, it's important to understand how the body uses energy. Chris Mohr, a registered dietician who has a PhD in exercise physiology, says the first source of energy, lasting just a few seconds, comes from the breakdown of adenosine triphosphate (ATP), which is naturally found in the body.
Next, the body uses glucose (sugar) for immediate but longer lasting energy. Finally, during endurance training, the body starts to break down stored carbohydrates, called glycogen, to provide sustained energy.
"The type of workout itself, and the duration, will affect the different processes taking place in your body," says Mohr. So the duration and intensity of your workout will determine your energy needs.
Knowing how to best fuel your body can help you get the most out of every sweat session and get you one step closer to achieving your goals. Here are the fundamentals to fuel for success.
