Dumb
This idjit could use less weight using a full ROM if he had a brain.
It's called keeping constant tension on the target muscle.
He's German so he probably has a brain.
You`re correct, but using it properly is a whole `nother animal. Either or......he looks like a bag of dehydrated foreskins.
That’s not really a variation. It’s just putting one dumbbell on top of the other.
Always stay hydrated.
