Product Overview
Strengthen your arms with the OB-48 Olympic Super Curl Bar designed to put your hands in multiple positions that targets muscles in the forearms and biceps. The bar has more prominent curls in the handle to allow for more forearm rotation which works the smaller muscle groups in the arms. The bar has a maximum load capacity of 200 lbs and includes locking ring collars for safety and security. This is a proven favorite for bodybuilders everywhere, because it gets results.
Features
BRASS BUSHINGSBushings fit between the bar and the sleeve, reducing friction between the outer and inner sleeve thus making the spinning movement smoother. Perfect for powerlifting style lifts.

2 INCH SLEEVE
OB-Series Bars accommodate Olympic weight plates with 2-inch center holes. The standard in sleeve size.

DIAMOND KNURLING
Diamond knurled grip areas for demanding workouts without slippage. Etchings are ‘medium-fine’ as most commonly found in commercial gyms. Safe and comfortable for solid grip, but not too aggressive that chew up your hands.
