WAY TOO many training days in there! You have a lean physique but you need to put on a lot more mass...You're hitting shoulders not even 24 hours after arms and then chest after that..I used to follow a similar protocol when I started lifting almost 7 years ago and was just chronically overtraining (which I still continue to overtrain and I'm not natural) ...not to sound like a dick, but it looks like you've been training for only 6 months tops with a good diet at least, but you are just lacking the size, even in physique....good luck, but you have a lot of work to do I a few months!
