What Makes a Great Squat Bar
A squat bar needs three things: stiffness (29mm+ shaft with minimal whip), aggressive knurling (to prevent bar roll on your back), and center knurl (to grip your shirt and keep the bar stable). Olympic bars and WOD bars with 28-28.5mm shafts and no center knurl are poor choices for heavy squatting.

Frequently Asked Questions
Do I need center knurl for squatting?
Yes, center knurl is highly recommended for squatting. It grips your shirt and prevents the bar from rolling down your back during heavy sets. Without center knurl, the bar can slip, especially when you are sweaty or wearing a smooth shirt. All competition powerlifting bars have center knurl.
Can I squat with an Olympic barbell?
You can, but it is not ideal. Olympic barbells have 28-28.5mm shafts with more whip, which can cause the bar to oscillate on your back during heavy squats. They also lack center knurl, increasing the risk of bar roll. For serious squatting, a 29mm power bar with center knurl is significantly better.
What is the best budget squat bar?
The CAP OB-86PBCK (around $140) is the best budget squat bar. It has a 29mm shaft, 190K PSI tensile strength, center knurl, and aggressive knurling. It is not as refined as the Rogue Ohio Power Bar, but it performs well for heavy squatting at half the price.
Why does bar whip matter for squats?
Bar whip (flex) is undesirable for squats because it causes instability. When you unrack a heavy squat, a whippy bar oscillates, making it harder to stabilize before descending. A stiff bar with minimal whip locks into position immediately, giving you a stable platform.
