Tensile Strength: The Most Important Spec
Measured in PSI — determines load before permanent deformation. <150K = budget, bends under heavy squats. 180-200K = home gym sweet spot. 200K+ = competition-grade. A 190K bar yields at ~120K PSI — enough for 700+ lb deadlifts.
Minimum Spec
For loads over 300 lbs: 180K+ PSI, 28.5mm shaft (men's), quality knurling. Everything else is preference.
190K PSI, 25mm shaft (women's), cerakote. Best women's bar.
