How much can he improve with 1 year full training.
About 50~60 %
Making those legs 50% bigger? Get a fuller back? Overall more filled up round muscles? 10 pound heavier? 15?
Yes. 15 pounds heavier, at least.
Top 10 Mr O? Could he qualify by his own doing a smaller pro show?
When his legs are +50~60 % and his back is fuller, he could definitely snag a Top 10 spot.
How much can he improve from here on? Will the body just blure out n look like shit?
Body will not "blure" out.
How much is the risk for healt issues? Can he be abel to train smarter and skip egolifting while he is groing and become stronger. I think that will be the main problem...lifting heavy n hardcore and get new ingjyries...he need to step back and change gym routine to pump/volyme training...
Risk for "healt" issues is high, but he is both Cain and abel to train smarter while Groinking.
