Answer 1

1 push up is pathetic, even if you are like 14 (judging by the pic).

Do as many as you can nightly. Try reach 2, then when you can do 2, go for 3 and so on.

The exercise you already do won't strengthen your bi/tri & elbows.

You could start lifting weights but I'd advise against it - judging by your age.
