The sweet spot of course duration. Too short and you forget everything, too long and you lose momentum. How Milo's format is built from learning science.
Wouter Middelbos
One of the questions I get most often: "Why does your course take 30 weeks? Isn't that long?" Followed by the variant: "Can't you learn the same in a few months?"
The honest answer: no. And the reason is not that we stretch the course to charge more. The reason is that your brain does not work the way you would like.
There are courses that give you a PT certificate in a weekend. Two days, done. And yes, you then have a piece of paper. But what have you learned?
The answer lies in science. Information you absorb in a short, intensive period is stored by your brain as "temporarily relevant". It goes into short-term memory. You can reproduce it on a test two days later. But two weeks later it is largely gone.
This is called the spacing effect, and it is one of the most replicated findings in cognitive psychology. Distributed learning works better than concentrated learning. Not slightly better. Fundamentally better.
The reason is counterintuitive: you need to forget something to remember it well. Every time you forget something and retrieve it again, the neural connection gets stronger. That process of forgetting and retrieving is not a bug in our memory. It is a feature.
A weekend course skips that process. You absorb everything at once, you forget it, and there is no moment to retrieve it. Result: you have a certificate but no competence.
On the other end of the spectrum: four-year university programmes. Four years of theory, internships, thesis. You learn enough there, right?
The theory, yes. But four years is long. Very long. And the longer a programme lasts, the greater the risk of losing touch with why you started.
I have seen enough university graduates who stood on the floor for the first time after four years of study and completely froze. Not because they did not know the theory, but because they had never felt the tension of a real client waiting for you. Four years of theory without regular practice creates a different problem: you know everything but you can do nothing.
Additionally: motivation is finite. A four-year programme demands a lot from your perseverance. Many students drop out. Not because they cannot do it, but because the finish line is too far away.
Thirty weeks was not chosen arbitrarily. It is the result of years of experimenting and adjusting, with science as the compass.
Thirty weeks is long enough for the spacing effect. You have multiple cycles of learning, forgetting and retrieving. The material you learn in week 3, you have partly forgotten by week 10. In week 11 you retrieve it, and it sticks better. In week 20 you use it in a practical lesson without thinking about it. That is anchoring.
Thirty weeks is short enough to maintain momentum. The finish is always in sight. Every lesson builds noticeably on the previous one. You feel yourself getting better, and that feeling keeps you going.
Thirty weeks is just enough to stand on the floor ten times. Ten practical lessons, every three weeks. Enough to develop real skills. Not enough to become complacent.
The three-week cycle is at least as important as the total duration. Three weeks is enough time to process a theory block, complete assignments, and let the material settle before going to practice. It is also short enough that you do not forget what you learned.
Every practical lesson is a test moment. Not in the sense of an exam, but in the sense of: can you apply this? Do you really know it, or do you think you know it? That confrontation with reality is the best teacher there is.
And after every practical lesson you go back to theory. But now you read it differently. The page about squat biomechanics that you did not fully understand in week 4 is crystal clear after coaching ten squats in week 6 and receiving feedback. Theory strengthens practice. Practice strengthens theory. That is the coaching loop.
The time investment is deliberately chosen. 8 to 12 hours per week, spread across the week. That is compatible with a full-time job. Most of our students work alongside.
But it is also enough to make serious progress. It is not "an hour a day when it suits you". It is a commitment. You reserve time in your calendar. You treat it as a job, not a hobby.
That combination of realism and commitment is deliberate. We want students who take it seriously. And we want those students to be able to combine it with their lives. Thirty weeks at 8 to 12 hours per week is the balance that makes that possible.
I did not have to write this article. Most courses just tell you how long they last and expect you to sign up. But I believe you have the right to know why something is the way it is.
Thirty weeks is not perfect. There is no perfect duration. Some students would benefit from more time. Others could have done it in 25 weeks. But if you have to choose a format that gives the best result for most people, this is it. Not because we say so, but because learning science says so.
And if you doubt whether 30 weeks is worth it: ask someone who has been through it. They can tell you more than any article.
Not just a certificate, but proof of real expertise!
