Gym members begged me for years to build them a cross over machine. When I finally installed one it wasn't used that much by the big guys. The beginners loved it, though. For chest training it is almost useless. Why? Well, when you use heavy weights the free standing movement becomes unstable and is dangerous. I don't recommend this for chest training. That doesn't stop the intermediate blokes who copy what they see in magazines. Oh, I forgot, you gotta hit the muscle from different angles! How silly of me.
Add the rope to the list of waste-of-time accessories in the gym.
