Cutler wasn't necessarily weaker than Ronnie. He just didn't focus on moving the weight
from A to B. You don't necessarily have to get any stronger muscularly to lift more weight.
You just practice the movement, in the rep range you want to get stronger at, being concious of the
poundage, always trying to increase it... that how you demonstrate strength.
All guys with big muscles are strong muscularly. They may not be able demonstrate it as well
as others though.
