A friend of mine competes in the 69kg class. He has arms just like this guy and is ungodly strong. He used to wrestle in school and then took up powerlifting. He did that for a number of years before switching to Olympic lifting at 30-31.
He has placed third nationally, he competed in the last Olympic trials, and he places between 1st - 3rd in his class quite frequently.
In college, he set a record bench press of 391 at 148lbs (in the late 80's).
Even though he rarely benches, he still does 315 for sets of five and can still hit 365 with little training. However, his focus is on O-lifting/competing, and he routinely snatches 115-125kgs and clean/jerks 140-150kgs.
He is the one I trained with when I also competed in Olympic lifting. Now, I train with him every now and then. As he has used my home gym for some workouts until his home gym is complete.
At 5'5", 69kg, he is thick and strong. Bastard.
