Don't you think Kang Ho-dong is actually incredibly strong?

When you see him on variety shows, he loses arm wrestling matches to regular celebrities and can't bench press 100kg.
But looking at his facial expressions and posture at those moments, it seems like he's intentionally pretending to be weak. Even if he's over 50 and losing muscle mass, I don't think it's possible for someone with that skeletal structure to be unable to do that.
And when he occasionally puts his mind to it (though of course, it's hard to do a 1-on-1 comparison), I've seen him lift a 200kg tire using just his waist and arm strength.
