How strong is the correlation between strength and muscle definition?

Question

For example, a 170 lb (70 kg) person with defined muscles versus a less muscular person.

In: 166

Answer 1

Muscle definition is far more directly correlated to body fat percentage than to strength. Men at 5% body fat tend to have very defined musculature, but lots of professional strongmen are just big everywhere (and a LOT stronger than even most high-level athletes). Compare an NFL lineman with 15%-20% bodyfat versus a cornerback or receiver with 5%-10% bodyfat. The linemen are typically far stronger, but the receivers and cornerbacks have far more defined musculature.
