Same. I found that picking up a 28-kg kettlebell and climbing up a 20-storey building within 6 mins (switching up hands every couple of floors) is an awesome "functional" exercise. Hits cardio, grip strength and unilateral stability stuff.

If you can haul a 60 pound lump up 20 stories, this article is not for you.

If you can't do that it definitely is a sign you don't exercise anywhere close to enough, I know 80+ years old who could still do this

Are you able to point out which video explains how to find your current bottleneck? I suspect its something I would find quite useful! Unfortunately most of the videos have quite "clickbaity" titles, which makes it hard to figure out what they are about.

On mobile RN. I'll try to find it once I'm on a desktop.

I had a distinct visual diagram in mind that I can't find again. Maybe my memory is fuzzy and mixed those two:

Can you really do HIIT on a treadmill? It doesn't sound safe to sprint on a machine. Re your observations. Are you referring to elderly people? I'm not sure this study is about them. My mental model of this mechanism is that relatively young people can choose between e.g. long distance running and sprinting, and that the latter will yield better cardiac outcomes.

In my experience HIIT works very well on a treadmill. Many treadmills even have presets for HIIT.

I guess it depends on your age and current fitness level. When I was young and fit, I could outrun the treadmill for the periods of time I needed.

The treadmill also wasn't able to change speeds fast enough to really do the good Sprint simulations

High-intensity exercise is obviously good, but beware of the trap of doing just high intensity exercise and doing it too frequently - the body does not handle that amount of stress particularly well, and it will be counterproductive to your health. Low intensity exercise that holds your aerobic base is vital as well - and for a well-rounded exercise week, it should constitute the majority of your exercise time. That…

Interval training also seems like a great way to burn out and make yourself dread the thought of exercise.

Other than for elite athletes tuning specifically for bursty competitions, interval training is such an unnatural torture that I do not understand the appeal. Even if the dubious popular claim that it is a short cut to optimal fitness might be partly true, I would much rather have an hour or two fun cycling or light running and exploring than 10 minutes of interval agony.

It's interesting that they characterize a 30-second cycling effort as "all-out" when any cyclist knows it's impossible to go "all-out" for that long. You can go really all-out for a few seconds before your whole metabolic process needs to switch modes. A 30-second effort has to be paced. "All-out" intervals are very effective but for me they mean 4 seconds out of every 30 seconds.

I don't understand your objection. Anyone who is not very frail could do maximum effort for 30 seconds. It's not going to be constant power/HR/whatever but the person can still go "all-out". Consider a bear chasing you, are you going to say that you will just go all-out for 4 seconds and then pace yourself?

There is a constant stream of pop-science/lifestyle-advice articles advertising HIIT as a way to save time on exercise along the lines of "this smart technique, developed by a Japanese scientist will make you as fit as someone who exercises 8 hours a week with just 4 minutes per day!". Search for "Tabata" if you are curious. So a lot of those, who find regular exercise too hard, try HIIT as a replacement.
