Nice thread..good info from all different angles.
I don't wanna come here as a newbie and give any advice, so please don't take this the wrong way, but I made a video with few different techniques I have found effective for adding strength. I do agree with Sandman that when looking for size, strength is not as important..I get bigger from lighter weights...but either way maybe you might see a technique you like in this? Just a few ideas for consideration
