Ever wonder why some struggle more than others?
Undeniably, our bodies are unique. Therefore, built differently. However, there is one essential thing all must have! The mind and body connection to use any body part at will. Without it, we have yet to be able to use it at will. How does this have anything to do with building up huge arms? If that is on your mind. Good! Time to get down to it! With a genuine, well developed mind and body connection. You can ever lift something with your own strength instead of momentum. After all, how would you like to be injured due to lifting improperly? If I were you I would ask myself such questions. While I have yet to build huge arms. I am far stronger than I used to be as a result.
To summarize everything. Only with a genuine, well developed mind and body connection. You can ever develop any body part well.
