Olympic Barbells for Cross Training. Cross training includes many exercises with a high number of repetitions, so the main feature you should look for is a medium or gentle knurl (without the central one) and a high retraction stiffness. Olympic lifting is usually done with a small number of repetitions and for this reason the knurl on many barbells is often stronger than necessary for cross training. It is also important that the barbell does not have a central knurl in order to protect the neck from potential scratches during the clean. And finally, a high traction stiffness is a good indication of the resistance strength of the barbell.
