Brad is strong, yes - but not as strong as Tunza Fallsview.
He has also been called out for using fake plates on YouTube, and essentially claiming to be stronger than he is. He is strong, so I see no reason why he has to fake it.
His box jump cannot be faked though, and I believe he did a dumbbell overhead extension with a 100-lb dumbbell pretty easily. Yes, he is strong. But the fake plates get annoying.
