He obviously can't look like that during the entire offseason 
Trust me!! thats when he was in his competing years! he was never out of shape and was always in great shape for a photo shoot or a guest pose. He was always within 4 weeks of contest prep!! Mind you he would compete any where from 3 to 8 times per year.
Even now at 250lbs he could easily compete at 240-245lbs!!
