Like high cal>es. The muscle attaches all the way up. Same with Jay. But if you look at old pics of both, their forearms didn't used to look that way!
Usually guys with high calves (black dudes) have high forearms---even Phil has high attachments, it's just that his are very developed, my dad and uncle same deal.
But, with Branch, it seems the muscles have atrophied--he uses straps A LOT, with could be a big reason...Lee Priest had said when he trained arms, he didn't use straps. I noticed my forearms got bigger and stronger when I trained arms without gloves that had forearm wraps built in or when doing shrugs without wraps...
It seems Branch, instead of building up his forearms, chooses to "strap it up", therefore the muscles don't get worked...
