We have a new grammar for communication. So it's very difficult for me to have a conversation with you guys, the listeners and say, oh, I rode up a hill today at 22 K an hour because you can't interpret that. You don't know the gradient of the hill. Was I riding with a tailwind? Was I riding with a headwind? It's very, very difficult for you to interpret and go, how hard was he riding? How difficult was that climb? He rode 22 K an hour for 10 minutes. What What does that mean? It's almost impossible to make peer comparisons this way, and it's almost impossible for me to give you a prescription to follow that way. So this is why we use zones, and this is why we use power. So if I say now I wrote in zone four at 400 watts for 10 minutes, everybody has a gauge. They know from the zone four, demarcation, that zone four is around my capacity. It's the most I can write for one hour, and now they know the power I wrote, 400 watts. So now they know the sort of power that I could hold for that's all for a period. This is super important for a coach. This is super important for me as your podcast host and you as the listener. So when I talk about training principles, I have a clear way of communicating them to you. I can say a sample threshold session is go right in zone two endurance for 60 minutes and in that 60 minutes add in two 15 minute periods where you're going to work in zone four. Now you have a clear prescription. And that's the power of breaking it down in zones. For us, the coach at the next step, what it allows us to do is manipulate intensities, rather than you going out and riding at the same speed all the time, we're able to, as in that example there, interspersed periods of intensity, say, two 15 minute periods in zone four. Why this is super important is everybody has a friend. Think about this one now for a second. everybody has a friend who's gone to the gym for, I'm gonna say two, three days a week for the last three, four years, they still have a belly, they still have love handles, and they have got not one little bit fitter. There's a reason this happens, they've hit a plateau. So how our body works is we initially get a stress, we get fitter in response to that stress, then our body is smart, we adapt to that stress. So once we've adapted that stress, we've stopped getting stronger. So what we need to do, our job as a coach, we need to change up the type of stress. So it's restressing, you're restimulating it again until you hit the next plateau and then it's rinse and repeat, like going up steps on the stairs. Up the step, plateau, up the next step, plateau. One of the ways this became super evident to me was very early in life, and very early in life. talking like an owl lad here. I was probably 16 and I was working on a building site and I remember when I started in the building site, I used to think I was super fit, you know. I had no idea what training was back then. I taught training three, four times a week for an hour, football training after school and run the couple of days a week in the mornings before school was super fit. But I was calling myself folks, but that's a story for another day, building sites and I come in from work and I would be like to say I was right off with fatigue was like doing it no justice. I was glued to the couch, couldn't even move. Never mind going to do anything. I limp in at 6 o'clock, fall on the couch, barely have energy to eat my dinner, fall asleep by about half-eight and this went till the next day and work. I've chatted the lads in work and to be this fairly heavy set placer and work them with, don't all the same work as me for the day.
