There are plenty of tips out there on how to plan and progress your training sessions. Based on different variables and theories.
If I can be a bit sarcastic, then majority of them is based on what the coaches/athletes are seining it on a YouTube (Facebook and Instagram too). I named this “YouTube periodisation”. Don’t lough, this is real deal and I am sure this is most used periodisation scheme these days. All the other ways of planning are way behind this one. Who cares for block, linear, undulating, conjugate, top to bottom approach, whatever named periodisation if he/she can easily access YouTube from anywhere on the world and just watch new exercise and add it to our plan.
