I think he misses the point. Had his discussion been about the training differences between power lifters and bodybuilders, perhaps he might have been closer to the mark. But for the general public, it was largely an irrelevant argument.If you have questions about how push ups make the muscles grow, then you will have to know the basic rule of muscle gain and that is - training against increasing resistance. Most people think that they can only create the resistance by lifting or pulling weights. Yes, lifting weights is one of the best ways for creating resistance but the other good way is to using your own Power Max 360. In place of external free weights or machine weights you can use your own body weight and create resistance training. Push up is one such work out.
