Do I have to lose weight?

I'm a teenager, 130 pounds or so and Im working out at home and in the gym doing crunches, benching etc. One thing I've noticed is that after some time, you could barely see my abs but I know they're there cause if I pulled some of the skin on the bottom of my stomach down you could see them. I think I'm a little bit overweight and a lot of it is mainly fat =\. How much weight do I have to lose to make my abs noticeable and make me healthy.(I get shortness of breath easily when working out)

you seem fine!!!

The way not to do it is starve yourself, to start with. Just exercise and eat right. I did....lost 90 LBS because of it. Starving yourself won't help at all. Drink more water, eat less before bed, and don't eat for stress are the 3 things I follow and i'm going pretty well if i don't say myself. 90 LBS isn't anything like 5-10lbs so take my advice. If you want anymore details, feel free to email me. Just please be patient for ppl seem to email me for advice on this, I will reply, don't worry! ~Adia
