Well, you should see my LP, Philly... It's called "the Log"... Now that is re-toping, I asked to make some weight relief holes on it...
The answer from the luthiers was "c'mon, you're massive" and I replied "yes, but I won't be 20ish forever ;)"
So I kinda agree with you, but being not make a single exercise in 2 years due the shoulder, I was telling the difference of having a body used to work out vs sedentarism...
I miss it daily, specially in carrying things, my muscles get tired pretty soon, as they are not used to do lots of work :)
