How to train low cost or just have an idea to how to train?

You need to select a different single drill every time as repeating a drill loses the full benefit of the training.

You even highlighted it. I don't understand how repeating a drill will reduce the benefit of the training? What is working for you, but not for me, and why?
I'm not trying to be offensive, I'm just trying to understand what you meant.

let me explain from my point of view @Toxcatl
Training has some small roll dice.
If you put a player to make the same set of drills for many times, you 'll observe that the results differ.
@Talsiman maybe has some right , meaning that if we use some different set (or unique drill), we "might" eliminate/reset the next possible bad dice.
Some kind of trick.

But really, if you want to invest some 100 greens to pump up a player, that's not gonna make some big difference.
