Galpin's practical VO2 max approach uses three kinds of work rather than one magic interval scheme. First, include lower-intensity movement that can accumulate volume without major fatigue. Second, perform truly hard work, often in intervals shorter than two minutes, where the reduced duration permits honest intensity. Third, use a sustained four-to-fifteen-minute effort that progressively reaches a peak by the end; in some sessions one such effort is enough. These modes do not all have to appear every week. Instead, inspect the month and ensure each useful demand has a place that fits the person's limitations, psychology, and other training. The portfolio works because it develops both the ability to deliver oxygen and the peripheral ability to use it while reducing dependence on any single machine or branded protocol.
Origin
Extracted from Modern Wisdom, where Andy Galpin outlined the three components he uses in real coaching rather than endorsing one VO2 max protocol.
Core principles
- 01VO2 max can improve through multiple valid protocols.
- 02Low, very high, and sustained intensities create complementary demands.
- 03A month is a better programming window than one perfect workout.
- 04Adherence and genuine effort matter more than protocol branding.
How to run it
- 1
Place the easy work
Schedule one or two lower-intensity movement sessions that can be sustained without turning into another maximal day.
Pro tip Choose walking, hiking, cycling, rowing, or mixed stations according to comfort and access.
Watch out Do not let every easy session drift into moderate fatigue.
- 2
Place the short hard work
Use short intervals that let the person produce genuinely high effort. Set enough recovery to preserve the intended intensity.
Pro tip Shorten the work interval when a person cannot honestly work hard for four minutes.
Watch out Very short sessions only deliver the claimed high-intensity benefit when the work is truly hard.
- 3
Place the sustained peak
Add a continuous effort lasting roughly four to fifteen minutes and build toward a peak by the end. One well-executed round can be the full main set.
Pro tip An approximately eight-minute machine effort can substitute when a measured mile is impractical.
Watch out Use a thorough warm-up before a maximal sustained effort.
- 4
Review the month
Check whether the month contains all three modes in proportions the person can recover from. Move sessions rather than declaring a week failed.
Pro tip Judge the pattern over several weeks, not from one missed workout.
In the wild
An exerciser alternates thirty-minute nasal-breathing sessions, short hard assault-bike intervals, and occasional eight-minute maximal efforts. The exact days move when work or recovery demands change, but all three modes remain represented across the month.
→ The plan supplies varied VO2 max stimuli without relying exclusively on a Norwegian 4x4.
Common mistakes
Searching for a magic interval
Galpin says many work and rest structures produce benefits; the branded protocol is not the mechanism.
Making short work merely moderate
Reducing duration without substantially increasing effort removes the tradeoff that makes short protocols effective.
Is it for you?
Best for
It is best for generally healthy exercisers building cardiovascular fitness alongside other training.
Not ideal for
It is not ideal for people who need individualized clinical exercise restrictions.
From the transcript
“if you don't know your problem my recommendation would be to do some one to twice per week of some lower intensity movement stuff”
“something that's going to be insanely high and so this is almost always less than two minutes duration”
“component three then is more of that middle ground give me four to 15 minutes of continuous work by the end we're going to Peg”
