What exactly is analog training?

So to me, it's...

I use this a little bit in the book and I'll talk about my own training in the moment where it's about going and getting the data afterwards.

So if you think about some of the signals that you can use while you are training that don't involve being told what to do by an algorithm or being told what to do by a power meter where its rate of perceived exertion is not perfect.

There is no, any proxy that's perfect.

All of the things we use to sort of target a workout as low intensity, moderate intensity or high intensity, we're all using proxies.

None of us have continuous lactate monitoring going on.

what? I'm just going to listen.
