Most periodization models or training routines seem very linear. You do X*Y reps with a certain amount of rest and supersetting or whatever. Then next workout you do the same thing but a little more difficult.
I’d like to contrast this with a more intuitive way of training (that people like Tsatousline, Steve Justa, Charles Staley) have talked about. If you look at Olympic lifters or people like Ed Coan you’ll often hear stuff like “I warmed-up and then I went for a maximum that day, and then I felt good so I did a few triples”.
Why should each training session be planned in advance? Why can’t you go in, and just train in function of how strong you are on that day?
