My target is to get bigger mass and muscles, and prove that i can get good muscles by not eating meat, i am really annoyed that everyone around me says, that i won't get far without eating meat.
Could you please suggest what i need to concentrate more on?
Yea those phrases people throw out are crap! I've never had meat before and I wrestled through high school. I got those same lines a lot. Till my junior year when I actually started getting stronger than most the guys around me. I think the same desire you have is what drove me as well. I think the real strategy is to stay interested in your goal. If it is always there with you, you will always be working towards it. Then what you eat, how you move, how you work out, what you think about etc.- all falls in line.
When I adopted this goal as a freshman in high school, I took a weights class, and supplemented with 1-3hrs a day at the Y. I started researching proteins and found myself flexing in the mirror a lot, looking to see some encouraging progress. I started listening and picking up on other guys ideas about building muscle, and pieced together my own strategy. One of the interesting things I found, was that when you think about all this, you simply flex more! And when you flex, you build muscle! Now after I do bench--> pecs --> triceps, and they're all good n' dead, I'll flex the the tri's as I move the muscle through it's range of motion for that extra top off.
You'll probably find that you'll eat for your muscle a little more, even if nothing in the diet changes. lol. Good luck, I think you have a great goal! I'd love to see more strong meat free folks out there!
