So usually, I would say each 1 hr, you would train cardio and practice match on HARD intensity. You would train cardio first and then use a green pack then train practice match and use a green pack (depends if your player is playing or not) to prevent the chance of an injury. I made 4 whole quality points on 1 player in about a week of doing this until I got really low on greens and lazy so i started to skip alot of sessions.
So generally, focus on ptraining one player or else your green packs will burn as fast as fire unless if you have heaps
