[ Diet & Fitness ] Open Question : This is my gym routine?

I'm not sure if my training is correct, I'm 15 years old btw. First thing I do when I get to gym is go straight to the Flyers, to train my pecs. 10 each set, 5 times. weight; 65-70kg After every 10 I do another 10 pushups for each set. Then I train my biceps, 15 each set, 5 times I do one arm at a time and I usually do 17.5 kg Then I go onto work my back, 10 each set, 5 times. Then afterwards I usually just go hit boxing bags and rumble with my friends in the boxing ring I've been doing this for about 5,6 months now. What else should I do to train the perfect body?
