Be confident and don't let something like that deter you from someone you like.
If a woman sees a man look at himself in disgust and has no self esteem and isn't confident she's going to already see that a relationship won't work out. Women want men who are confident in their abilities and goals and life.
If you're unhappy with your current weight standards. Eat healthier and exercise often. Diet alone is key to losing weight. Exercising just sculpts you, makes the process a lot quicker.
I'm at that point in exercising where I enjoy the pain. I use to do it to look good but I do it to feel relieved of stress and because in the gym and in any athletic situation I am truly me. Athletics define me.
