Some very very impressive arms here.
Measuring arms . . . same time of day if monitoring progress (arms are their biggest
upon waking); measure cold -- no pump, first flex, at a right angle to the bone, arm
parallel to the ground, use a thin strip of paper . . . mark the paper with a pen where
overlapping occurs and then record the length using a steel rule.
And just for comparison.
Sergio Oliva, who's arms where as big as his head 'only' measured 20.5 inches.
How many people have flexed arms that are as big as their head? The size of
the average man's head is between 22 and 23 inches.
Arnold' arms pumped were 19 3/4 inches.
It's all appearances. Numbers means nothing, it is how they look.
Never seen a judge bring a tape measure on stage.
