What did rocky marciano used to eat and what exercises he did?

Answer 1

"This relatively brutal new regimen included a minimum of seven miles of roadwork per day, wearing very heavy training shoes that were specially designed for him by a local shoe magnate and admirer. On their frequent sunrise excursions through Rocky's favorite trail in Field Park, Allie often encouraged Rocky to run as fast as he could up the park's steep Tower Hill"

I've never heard that Louis and Marciano trained with Charles Atlas.

"We never hear of it. He would run a minimum of 7 miles a day sometimes 12-15. His trainer Charley Goldman worked on his footwork with him and he did alot of swimming. To see details of this check out web sites concerning Goldman and Marciano."
