four weeks out,I would have thought he would have been alot harder myself , idealy you want to be at your desired bodyfat levels 2 weeks out, I can see a lot of dehydration being used for the show, as he looks to still be carrying 3-4% to much body fat !!!
Then you run the risk of coming in stringy by trying to rid the last %s of bodyfat to fast as your time dwindels away !!
Just a obsevation from the photos, but I am sure bob will have it under control , I hpoe any how
