Interesting, the continuing dogma and alligiance to weights. Sure, BBs and powerlifters got the way they did using weights, but that's all there was then, or at least that's all that most used.
To me, the best leverage machines, and not just Hammer, meaning the best designed ones from any company-are better than weights. Each company's machines have to be tried to see which are best. If well designed, they're more intense, more direct, more to the point and more efficient at creating growth. I say this after using weights for years and years. Leverage is best, but the weight stack versions are also excellent, if again they're properly designed and if they allow the user to adjust for their body type.
