This is nonsense. Like people saying oh you can lose weight by being cold or breathing harder/more. Sure there is science behind it but in the end it does not promote maintainable lifestyles.
One minute all out may help athletes already in shape push to the next level. Like at the end of my long distance runs, I do a wind-sprint all out.
But regular people doing regular exercise benefit much more mentally from learning HOW to exercise for 45 minutes every day and increasing their metabolism.
If intensity training for a minute was all you needed, you could do sprints in the parking lot to train for a 45 minute 10K. Good luck with that.
Intensity training is good for fast-twitch muscle. Endurance training is good for slow-twitch. The two are not interchangeable.
