This is a Mercury & Thor original! Grow your forearms with this unique bar by doing three distinct classes of exercises, including...
Pulling: backwards sled dragging ("treat" your forearms while getting a total body work-out), overhead cable pulls, cable rowing, etc.
Curling: standing cable hammer curls (check out the May 2016 Exercise of the Month) , cable preacher hammer curls, cable upward wrist curls
Extensions: cable tricep extensions, cable downward wrist curls, hybrid extension/wrist curl (awesome!!)
Your forearms deserve a good thrashing, so get this one-of-a-kind bar today. You'll be glad you did, at least after the soreness goes away.
