Usually Kevin doesn't start training until about 13 weeks out this time he started long before that. OK take into account his age but his upper body seems to be responding like the old days which I never had a doubt it wouldn't. If his legs are responding even at 90% that's good enough. No one on that stage other than Ramy will have mind blowing legs.
Oh and just as a side note. Yes Phil does pretty much have the best BDB on stage but that's now, lots of guys back in the 90's had better backs. I'm really not impressed with Phil's back.
