The decision to use an Olympic barbell with or without center knurling depends on the specific needs and preferences of the lifter. Center knurling can provide additional grip and stability during back squats and front squats, which can be beneficial for some lifters. However, for movements like deadlifts and cleans, center knurling may cause unnecessary discomfort and abrasion on the lifter's neck and shoulders. Ultimately, the choice between center knurling or no center knurling on an Olympic barbell should be based on the individual lifter's comfort and the specific exercises they will be performing. **
