Reverse barbell preacher curls help build bicep thickness?

Does doing reverse barbell preacher curls, as seen here, help build bicep thickness (the brachialis)?

i really feel it in the forearms not so much the biceps

yes the upper forearms, i know your using your bis but iv always used it for forearms, well i never use it but if i did thats what it would be for:D

yea i dont consider it a bicep lift.. bc ive never gotten any bicep pump from it, just forarm..

"Hammer" movements are what you want to employ for Brachs IMO.

They are an excellent isolation exercise for the brachialis. I love using the preacher bench for curls; it really minimizes cheating. The only problem is maintaining the grip when carrying the exercise close to failure. Sometimes, your grip will give out first. If you're not concerned about grip strength, use some wrist straps to prevent this from happening.

my grip doesnt give out.....i dont find that reverse preachers hit the bis that well

I hardly hit my bis at all with reverse preachers... The forearms get killed though. Its great for forearms.
