Bryan Johnson does HIIT three times a week: two 4-minute sprints at 90-100% max heart rate, 4 minutes rest between them. The whole session takes 12 minutes and targets VO2 max.

If I wanted to get better at VO2 max, like, what is the way to do that?
Three times a week, I do four minutes of high intensity training. So heart rate between 90 and 100% of max heart rate for four minutes, rest for four minutes, then max for four minutes.
So that's only 12 minutes three times a week. Now it's an intense 12 minutes.
Yeah. So 16 minutes total. When you're at the 90 to 100%, it's intense.
