> training for professional endurance athletes has drastically changed in the last 5-10 years
Not by drastically changing their plans to reduce the hours and do HIIT instead.
Endurance training is what you do in endurance sports. A long distance runner needs to put in the miles. Hours after hours of running. That's it. Cyclists are on their bike 5+ hours regularly. Rowers do 10 sessions of 2+ hours a week, only few of them at high intensity. It's the hours that bring you the medal.
In fact, in order to be able to perform those long hours, endurance athletes typically force themselves to keep he intensity down. You can go hard for an hour or two, but then you need a rest day next day. You won't make it to the Olypics on 3-4 sessions a week though. So, you need to be smart and tune the intensity so that after your morning 2h distance piece you can actually meaningfully push some weights in the evening and be fit next morning for the next piece.
These 10-min HIIT "hacks" may be better for sedentary people than not doing anything at all. But they are not a silver bullet. To get anywhere, you need to put in the hours. No way around that.
