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

I’m a big beefy muscular beast.

There’s definitely a decent correlation, but it’s only indirectly causal. As others have said, definition is more about leanness than strength. However, big muscles are harder to cover uo with fat, so in practice, stronger muscles are usually more well defined. At 170 lbs, the correlation should be incredibly strong. Fat guys who have a bunch of muscle and fat are a pretty extreme and rare choice in physique. Most muscular guys choose to be a little bit cut and that strengthens the correlation.
