Sport Need help...Need to loose 15 pounds ASAP

[Tacoma750]

Im looking to loose 15 pounds. But I need to do it by mid june. IM 17 and im 165 pounds. Im just starting to go to the gym, but im really only doing arms/chest/back. I use the situp machine. Put 50 pounds on it and do 3 reps of 50. Butrns like a mother and I can see the outline of my "abs" under the fat i want to loose. Whats the best way to loose the weight? Should i just run like theres no tomorrow. What do you guys suggest? Im not huge, just a little chubby

Well... losing those 15 pounds isnt only about exercise. You have to have a lean healthy diet also. Why dont you post your diet and then maybe more people can help you.
