Compare the Northern Olympic Barbell 15kg and the Olympic EZ Bar Advanced Package to find the right bar for your home gym goals.
Quick answer
Choose the Olympic Barbell 15kg if you want a versatile straight bar for compound lifts like squats and deadlifts. Choose the EZ Bar Advanced Package if your priority is targeted arm training with included plates and an Arm Blaster.
Straight bar vs EZ bar: the fundamental difference
A straight Olympic barbell lets you perform a full range of compound movements — squats, bench presses, deadlifts, rows — because the bar is symmetrical and accepts standard 50mm plates. An EZ bar has a wavy, angled grip that reduces wrist and elbow strain during curls, skull crushers, and other isolation exercises. The choice comes down to whether you need a general-purpose bar or a specialist arm-training tool.
What each package includes
The Olympic Barbell 15kg is a standalone bar. You supply your own plates and collars. The EZ Bar Advanced Package bundles an ergonomic EZ bar, an Arm Blaster (a strap that locks your arms against your torso to prevent swinging), and a 37.5kg cast iron plate set. If you are starting from scratch, the package gives you everything you need for dedicated arm work right out of the box.
Weight and progression
The Olympic Barbell 15kg weighs 15 kg and can be loaded with additional plates as you get stronger. The EZ bar itself is lighter, but the package includes 37.5 kg of plates, which is enough for many intermediate arm workouts. If you plan to lift heavy on compound lifts, the straight bar offers more room to progress. For arm isolation, the included plates are a solid starting point.
Trade-offs at a glance
- Versatility: The Olympic Barbell 15kg supports squats, presses, deadlifts, rows, and more. The EZ bar is best for curls, triceps extensions, and pullovers.
- Included gear: The EZ Bar Advanced Package includes 37.5 kg of plates and an Arm Blaster. The Olympic Barbell 15kg is sold alone — you must buy plates and collars separately.
- Joint comfort: The EZ bar’s angled grip reduces stress on wrists and elbows during isolation exercises. The straight bar can cause discomfort for some lifters during curls or skull crushers.
- Space and cost: The Olympic Barbell 15kg costs less upfront but requires additional investment in plates. The EZ Bar Advanced Package is a complete arm-training solution in one box. Consider your total budget and whether you already own plates before choosing.
