Legs will definitely be better this time, but better dosent mean great legs...he would probably have bigger legs but I doubt they will look good...and the back...I cant really see when he had time to get that up again...to bring up a bad muscle group u need like 1-2 years of full commitment day in day out...no rest...I think he should take some time of after the show let his body rest for 3-4 months...and then do it all again...but first, lets se how he look onstage, if he looks better I think he could make it one more year...but he should definitely consider more strikt contraction higher volume training like most of the other pros does...training like that will make your body last all your entire life...
