You aren't over weight, but yes you are on the heavy side. (no offense) If you lost say 15 pounds or so you would be just fine. I am almost 5'1 and i weigh about 110. A 5'3 person should weigh about 125-130. So looking that that you aren't over weight as well. Also, i could mean u have really heavy bones. The best thing is consult the doctor. I used to be almost 120 and i cut down on soda, pizza, chips, chocolates- and did very little exercise. So if you taking in too much sweet that could be a reason. If you don't really want to cut down your eating habits you should probably engage yourself in 1.5 hours of exercise every other day. You should jog on the treadmill on a slow, steady pace, but for a long time- because that rhythm helps you lose fat. Also, try sit-ups/crunches or even cycling. Visit the aol.com fitness page and see they have any exercises you might like. And, last, talk to your doctor! Don't do any diet plans before talking to a professional.
