Product Overview
If Arm Day is your favorite Gym Day, the Synergee 2" Diameter Sleeves Knurl Curl Weightlifting Multipurpose Bar will be your new best friend. This bar is ideal for isolated bi and tri exercises, and perfect for accessory work for pull-ups, rowing, climbing, grappling, and developing upper body stabilizer muscles. The Synergee EZ Curl bar will get you the Michelle Obama arms you want; and soon enough, you’ll be flex-pointing in the direction of The Beach with confidence.
We designed this bar with you in mind. The curves allow you to do more reps with less strain on your wrists; because less room for injury means more room for gains! This design allows your wrists and elbows to remain in a more natural position for curls, rows, or skull crushers, and directly engage of your upper- and forearm muscles.
WRAPPED WITH CARE
To prevent unnecessary damage during shipping, all barbells are packaged in a thick cardboard tubing. The packaging is topped off with a special end cap that is tough enough to survive shipping, but is easily removed for unpackaging. As a bonus, each bar is wrapped in an anti-corrosion bag.
Due to global supply chain issues, items may be delayed 1-3 weeks.

Features
•SMOOTH MOVING BUSHINGSOur Curl Bars are designed with powder coated bushings to rotate seamlessly during your reps. From curls to extensions to raises, this bar answers smoothly and responsively to your motions. These bushings provide the right amount of spin that complements isolation exercises to build strength, add definition, and target your favorite muscles.
•SLEEK FINISH & GREAT GRIP
The Synergee EZ Curl Bar comes in Chrome, Black Phosphate & Cerakote. It gives the bar a sleek, clean look while protecting the steel from oxidation and wear. The knurling on the bar adds grip without being too sharp and helps reduce slipping during your reps.

• and – most importantly – wipe all moisture and liquid cleaning product from your barbell after following the specified contact period
If your barbell arrives defective or rusted, we will be more than happy to address your concerns. You must contact us within 5 days of receiving your order for a replacement. Any inquires after 5 days will NOT be eligible for a replacement.
