You shouldn't do anything momentarily. You are a little childish for serious exercise(the one you do in a gym). The item is, you are still growing, and if you workout your muscles intensely, they will remain in a state of contraction. When you grow within length, your bones actually do the growing, so if your muscles remain contracted, they will verbs on your bones, forcing them to stop growing, so you will stop growing.
The best way within my oppinion to develop a harmonious body is to practice a sport. You could try swimming, it's the best at your age.
umm heres a thought! work out!
Masturbate regularly and be sure to use both arms otherwise the final result may come out skewed.
Go jogging and swimming habitually. Do not use metals and artificial ways of building muscles. Running and swimming can benefit ALL your muscles on you, never mind just biceps or triceps. And finally, do some pushups and pressups during respectively exercise. You will not only build muscles adjectives over your body, but also you will have tangible strength in you! (some body builders hold nice muscles, but can't even run or wipe their asses properly...)
By straining them.
Hit the gym. You could start by running and lifting some weights at home first until you build confidence in yourself and they hit the gym! Good luck!
