Getting fit with SwordsMaster

[LeftEyeNine]

Yo ladies,

I have decided to grow my arm muscles a month ago and I have been doing the illustrated exercise once a day since then for each arm seperately, with a 7.5 kg weighing dumbbell, started at 40 repeats and increased to 50 for the last 15 days. Yes, I have a weak arm and yes, I know nuts about gym jargons. That's why I illustrated which basic exercise I've been doing for the past month:



On a protein-dedicated diet, this stuff really improved my arms' shape and power only in one month, however I need more variation of this. Because I want to improve the side parts of the upper arm and the whole forearm. I bet you have suggestions on what I can do, considering the amount of weight I have been lifting already which I have adjusted absolutely close to my limits and will be pushing forward as I improve. I know the golden rule : You need to push your limits to stimulate muscular improvement.

And also what kind of weight-lifting schedule do I need to improve the illustrated part below. In Turkish we call those muscles "wings", which are located at your back and actually are the side parts of that masculine "triangular" look. (marked with red arrows here):



Some people said that I'll need bench press to aim that which sounds reasonable. I just want to make sure and hear of other options, if there are.

Thanks in advance.
