Mubashar, I dont know why you saying all that stuff, because he didn't ask that.
rahmawan, Only way for condition decrease every day is Very Heavy training, there is no other way for condition daily decrease (Playing games decrease condition too). So please check again your training, maybe you accidently left his training to very heavy, if so, please change to medium and save. If training is already medium, then is some kind of bug, please contact admin or report bug through game.
