Buy Now · $49.99

The CAP Barbell 47-Inch Olympic EZ Curl Bar is a budget-friendly, solid steel curl bar built for isolating the biceps, triceps, and forearms. Cold-drawn from 51,000 PSI tensile-strength steel with a black powder coat finish, its angled 25.4mm shaft reduces wrist and elbow strain compared to a straight Olympic barbell during curls, preacher curls, and triceps extensions. Diamond-knurled 13” grip sections on each side provide a secure, non-slip hold, and rotating bushing sleeves cut down on hand and wrist pressure. It accommodates 2-inch (Olympic) weight plates only, ships with T-screw collars included, and carries a 200 lb weight capacity – plenty for isolation work, though a ceiling for lifters chasing heavy preacher curls or close-grip pressing. It’s a no-frills, no-nonsense pick for a home gym on a curl-bar budget under $50, though the bushing (not needle-bearing) sleeves and 1-year warranty mark it as an entry-level accessory bar rather than a commercial-grade one.

What is a Barbell?

What a barbell is

The barbell is the center of a strength gym — the bar you squat, press, deadlift, and clean with. A men’s Olympic bar is 20 kg (44 lb) and 7.2 ft long (15 kg / 6.5 ft for women). The specs that matter: knurl (the grip texture — aggressive for pulls, milder for high-rep work), shaft diameter (28–29 mm for barbell lifts), sleeve rotation (bushings are fine for slow lifts; bearings spin fast for the Olympic lifts), tensile strength (~190k+ PSI resists bending), and coating (bare steel grips best but rusts; stainless and Cerakote trade grip for corrosion resistance).

Which one to buy

For general lifting, a multipurpose bar (28–28.5mm shaft, dual knurl marks, no center knurl) does squats, bench, deadlifts, and the occasional clean off one bar — this is the right first barbell for most home gyms. Choose a dedicated power bar (29mm, stiffer, aggressive center-knurl grip) only once you know you’re training squat/bench/deadlift specifically and want the stiffest, grippiest tool for that job. A dedicated Olympic weightlifting bar (needle bearings, more whip) is worth it only if you clean, snatch, or jerk regularly.

Beyond your main bar, specialty bars solve specific problems rather than replacing it: a safety squat bar shifts load off sore shoulders, a trap/hex bar takes stress off a cranky lower back on pulls, and a curl bar’s camber reduces wrist strain on isolation work. Add them once you know which problem you actually have.

A dependable budget Olympic EZ curl bar: cold-drawn 51,000-PSI steel, a T-screw-collar package, and an angled grip that GarageGymBuilders calls “the obvious pick” for lifters under a $50 curl-bar budget. Its standout dimensions are value and versatility – it isolates biceps, triceps, and forearms across curls, preacher curls, and extensions on any standard 2-inch Olympic plate. Build quality is the weakest dimension: an independent hands-on reviewer found a loose rattle inside the bar and wobbly end sleeves straight out of the box, and Garage Gym Reviews notes some units’ bushings rub after months of use. It’s not a bar for advanced lifters chasing heavy loads – the 200 lb capacity and bushing (not needle-bearing) sleeves cap its ceiling.

  • +Functionality: angled ~30-35 degree grip reduces wrist and elbow strain versus a straight bar while isolating biceps, triceps, and forearms (GarageGymBuilders, manufacturer)
  • +Build quality: solid (not hollow) cold-drawn steel rated to 51,000 PSI tensile strength, with a diamond-knurled 25.4mm shaft (manufacturer, Garage Gym Reviews)
  • +Value: budget pick under $50 that GarageGymBuilders calls "the obvious pick" for lifters who already own Olympic plates (GarageGymBuilders)
  • +Versatility: works for curls, preacher curls, triceps extensions, and rows, with T-screw collars included and standard 2-inch Olympic plate compatibility (manufacturer, Garage Gym Reviews)
  • Build quality: an independent hands-on reviewer found something loose rattling inside the bar and wobbly end sleeves straight out of the box (YouTube: hands-on unboxing review)
  • Durability: bushing (not needle-bearing) sleeves, a 1-year warranty, and some owners reporting bushings rubbing after months of use (Garage Gym Reviews)
  • Value: 200 lb capacity limits heavy preacher curls and close-grip pressing for advanced lifters (GarageGymBuilders)
  • Functionality: light-to-medium knurling needs chalk in humid conditions, and the finish shows wear in humid, unheated environments over time (GarageGymBuilders)
