Query for those who power train their players

Have you noticed decreasing returns the long you train? (I have)

Also, injuries *almost* invariably happen when going 2x at stretching for me. How to break ankle this way I dunno, yet.....
anyone else notice patterns while training?

I find some players do better, consistently, at one type of training only. (Ive started a chart so i can take advantage and only train each in their happy place.)


going to repost this elsewhere and see if i get a responce.
