Alicia Mackey Huber describes a fitness technology that raises VO2 max by 12% in six to eight weeks using three five-minute sessions weekly, versus a spin class's 2% gain from 45 minutes five days a week. Six times the improvement, no sweat, no yelling.
With this technology, if you do five minutes of exercise that doesn't require any sweat and isn't even hard three times a week to get that slope of the curved signal into the body, you will get, in about six to eight weeks, about a 12% improvement in VO2 max. That is astounding. And if you were to instead go to a spin class where someone's going to like, wear spandex and yell at you while you sweat for 45 minutes, you do that five days a week, you will see a 2% improvement. So you're getting six times more improvement in a tiny fraction of the time. And no one had to yell at you while you were sweating.
