"If we’re talking about a hierarchy of training tools, I think a much better alternative to the barbell is the dumbbell. The kettlebell would be the next step up, as it can be used for both compressive and traction-based lifting/swinging. I think the clubbell is an even better training tool than that. Of course, the king of all strength training tools is the body itself."
