Overview
This 47 inch Olympic EZ curl bar is built for 2 inch plates, with rotating sleeves, two spring collars, and a curved profile meant to ease wrist strain on curls.
The bar is a single piece of chrome-finished alloy steel with no assembly required, rated to hold up to 370 lbs, with 31 inches between the collars and 7.1 inches of knurling on each side. The curved shape is the main functional point: it lets the wrist sit at a more natural angle through the range of motion than a straight bar allows.
- Curved EZ profile for a more natural wrist angle
- Rotating sleeves sized for 2 inch Olympic plates
- 370 lb weight rating on one-piece alloy steel
- Two spring collars included for quick plate changes
Who it's for
Fits home gym owners who already have Olympic (2 inch) plates and want a dedicated curl bar without buying a full barbell set. Anyone using standard 1 inch plates needs a different bar, since the 2 inch sleeve will not fit them.
Strengths and trade-offs
Drawn from this product's published specifications.
- Rotating sleeves reduce wrist strain during lifts
- One-piece alloy steel construction, no assembly needed
- Rated to 370 lbs with 2 spring collars included
- Knurled grip sections on both sides of the curve
- Only fits 2 inch Olympic plates, not standard 1 inch
- 47 inch length limits use to curl-style movements rather than full barbell lifts
Performance notes
The rotating sleeves let the bar spin independently of the plates during the lift, which reduces the torque transferred to your wrists compared to a fixed sleeve. The curved bend positions the grip at an angle partway between a straight bar and a dumbbell, the standard reason lifters choose an EZ bar for curls and skull crushers over a straight barbell.
