To get muscles like Arnold, it's going to take much more than just training. It requires a very scientific formula that's specific to your body. Don't expect to follow Arnold's workout routine and end up looking like him. It won't happen.
Like most bodybuilders, Arnold had a very intense diet where he consumed a ton of calories, lots of protein and carbs. He also did steroids, which were legal at the time when he was competing, and that alone puts him at an advantage that most people can't come close to without some form of enhancer.
Regardless, Arnold is an inspiration to all of us. He set goals, created a plan of action, and he accomplished them. That is what you need to do if you want to be successful at bodybuilding or working out. Create a strict muscle building program for yourself, and follow it. Eat properly, train according to your body type, let your muscles heal - rinse and repeat. You will get bigger if you do it properly. It's just simple science.
Now, go get swole!
