Who do you look for?
Anyone with good technique and dedicated to their workout routine.
Who trains the hardest?
Impossible to ascertain, since weight load is relative and dependant on many factors, as are days available to train etc...so too many variables.
Who trains the most?
Difficult to say, depends on time available to people.
Who is the most dedicated?
Impossible to say, and it's impossible to say that anyone is not dedicated; if they're lifting that's what counts, for me anyway.
Who at the top of your MAB list?
Nobody in particular.
36.5 kg /80.3 lb Middle-Finger DL (right hand)...
