There is training hard, and then there is training hard efficiently. Ultimately, as much as anyone can manage, they must absolutely make training as measurable-by-numbers as possible. You don't want things to enter the realm of linguistic vagaries. If you do, you have macho-minded wrestlers thinking they "worked hard" when the only muscular stimulation they did was equivalent to deadlifting 100 pounds.
I guess it was a bit unfair for me to say that "suplexing people is ineffective", but the point remains. Training in a controlled environment, controlled intensity, controlled volume, controlled pacing, is far more effective than random hard work in some activity.
For example, although I would never doubt that hard-working manual laborers like farmers or construction workers are strong and have gotten strong through their hard activities, I would still consider formalized weight training to be much more effective than what they do. In formalized weight training, you get to measure stuff. And that's extremely important in training.
