This is Troy Barbell's Bigger, Heavier, Commercial Curl Bar

Despite popular thought, your biceps aren't going to grow on their own! Isolation exercises such as barbell curls are the most effective way to grow your "guns" and the Troy EZ Curl bar is the perfect bar to get it down. You can also blast triceps and forearms with moves like skullcrushers and reverse grip curls. This 60" (5 foot) commercial quality curl bar is a 30 mm bar with a black painted finish and deep diamond knurling for comfort and grip. A curl bar is essential to a "complete" gym whether it be in your garage or in a commercial location.
