there is only 1 training, so only friday matters. If the training is only maximum on friday, the players train on maximum.

advice: Never train anything else than averge.

training occurs once every week. So thats the only time the energy level changes.

If you want to play aroun with the trianing settings, you can set it to maximum for 1-2 weeks and then back to normal or lower till you get your player energies back to normal.

A lot of ppl would advice against it unless you are in a all-bot league. I consider it a strict no-no once you have coaching staff. (I would say ideally you shouldn't buy coaches till you hav finished vip and executive seat constructions)
