How can I tone my body to look ABSOLUTELY amazing in a year ?

I am 5"2 , and out of shape but for some reason have always been that way no matter what sport I joined. I am 184lbs and I need to lose it ASAP. I would like like to get to at least 130. Which means I have to crack down but , I want my body to be in the best shape it has ever been in in 18 years. HELPPP!!!!
