For arm-focused home training, this standard-sleeve curl bar has sensible specs, but it won't suit lifters already on an Olympic 2-inch system.

Overview
At 47 inches long with a 25mm nickel-plated shaft, the ExtreSpo EZ curl bar curves for wrist comfort during arm training and holds up to 220 lbs on its 1-inch sleeves. Two star collars ship with it for securing standard weight plates.
The curved shaft is the point of the design, meant to put the wrist in a less strained position than a straight bar during arm work. It takes 1-inch standard plates rather than 2-inch Olympic sleeves, so it's built for home or garage setups already using standard plates rather than an Olympic rack.
- 47 in length, 25 mm diameter shaft
- Holds up to 220 lbs on 1-inch sleeves
- Nickel-plated, diamond-knurl grip
- Includes 2 star collars
Who it's for
Suits home and garage gym lifters doing biceps, triceps, and forearm work with a standard 1-inch plate collection. Not a fit for anyone building an Olympic 2-inch setup.
Strengths and trade-offs
Drawn from this product's published specifications.
- Curved shaft reduces wrist strain during curls and forearm work
- Nickel-plated finish resists rust and oxidation
- Diamond knurling for grip without excess sharpness
- Includes 2 star collars sized for the bar's 1-inch sleeves
- Only fits 1-inch standard plates, not 2-inch Olympic sleeves
- 220 lb weight capacity may not suit advanced lifters
- No customer reviews yet to confirm long-term durability
Performance notes
The curved shaft shifts the hand angle to reduce pressure on the wrist compared with a straight bar, and diamond-pattern knurling is there for grip without being sharp enough to tear skin. The nickel-plated finish is meant to resist rust and oxidation over time, and two steel swivel-socket collars hold plates in place on the 1-inch sleeves.
