My age is 25 and weight is 50 kg. My problem is my fat legs. My upper body is slim but my legs are comparatively very fat. I don't exactly remember when my legs got fat but I noticed it some 5 years ago. It is very much visible in photographs also. I tried different exercises for hours but nothing worked. I have no other problems with my legs, the only problem is that they are very fat. I don't have thyroid. Please tell me why my legs got fat and how can I make my legs slim and look normal.
