No biceps u say? 
You poor poor man. In the face of hundreds of pics showing yates mediocre biceps you post ONE declaring otherwise.
Think for a minute will you about the hundreds of pics of yates biceps where they look shoddy compared to the sparse few where they don't look half bad.
Think then what could the possible reason be behind the overwhelming outnumbering of the former over the latter, bad angles, poor lighting, a conspiracy perhaps?
When you realise the
true answer you'll never post another pic again.
Heres a hint: its because they SUCK!
