- Precisely why I also said this… (bold for emphasis and direct relation to your comment)
In a perfect world, they would all be reasonably close. In reality, personal training history, physiology and psychology lead to varying results. That’s why people should test a bit, find the one that suits their situation, a stick with it from that point forward.
I see a fair bit of FTP test surfing with people jumping from wave to wave. I think that is counterproductive in many ways.
And by “find the one”, I mean try any and all FTP test methods. See how they give you an FTP and if that leads to productive workouts, and then stick with that particular test.
I never recommend to blindly take one and not look at the results.
