How do I get toned in about 4 weeks?

Hi i'm 16 years old male (just turned on the 15th yay for me!) and i would like to know if there is a way for me to get toned in about 4-5 weeks i'm 5ft 8in and 114lb so as you can imagine among the slimmer set. Ive tryed a lot so far like crunches (the max i did was 300 for the crunches and 160 for the curls) and bicep and tricep curls ect. but with a lack of results... so like i said i would like some suggestions if you people could give me some i would appreciate it. P.s. ive tryed to get more protien intake so any dietary suggestions are appreciated as well. Thank you for your help!
