I guess when someone can do five reps of one armed push ups, five reps of pistol squats and five reps of pull ups (one arm?) then they can say "well, maybe time to drop this scheme and hit the weights"#. But the vast majority of people don't come close to this, so it is completely and utterly absurd for the grandparent to dismiss anything other than barbells for strength training. #Admittedly it's hard to find a replacement for something like olympic barbells when it comes to exercises such as the deadlift. And of course weights have their benefits with the easier progression, etc etc...
