Goldberg has had a pretty good run this time around, but at the age of 50, it sure hasn't been all fun and games to get himself back in the ring.

Goldberg was a guest on the premier episode of E&C's Pod Of Awesomeness and on the show one of the things he talked about was how brutal his regimen has been and how he has been miserable this go around - but it has all been worth it:

"I am nothing but a machine now. I get up in the morning. I eat. I train. I eat. I go to the bathroom about 20 times intermittently throughout the day because I'm shoving 15 to 20,000 calories in my body and it doesn't know what's going on. At 50 years old, it has no idea..."

"It's the toughest thing I ever embarked upon, guys. I'm 13 years removed from the business." Goldberg added, "I can't name a power wrestler who has come back 13 freaking years afterwards. And then, within 20 pounds of what he was back then..."

"People are expecting me to be able to do exactly what I did back then. Well, I mean, let's be honest, man. I forgot how to go through my pyro! I honestly, I swear to God, I actively, when I came back to the WWE, each and every time I went through Gorilla [position], I would remember another thing that I had forgotten in my preparation..."

"I'll be honest, I'm miserable. I'm absolutely miserable. But my family's having fun, man. And so, every single thing, every training session, every ART massage that makes me cry, every muay thai session, it's all worth it, man. It's just worth it. And, hey, at the end of the day, if I want to smile, I'll buy a car. That's how I'm happy. I did, I bought one on the way back from [Survivor Series in] Toronto because I worked my ass off..."

"Nobody get me wrong when I say I've been miserable throughout this, but I am. I'm miserable. I'm bloated 24 hours a day. I'm stressed 24 hours a day. I don't sleep, but it's a small price to pay."

"For me to be 237 [pounds] and have great cardio and then get the phone call that six weeks later, I've got to do what I've got to do. Do you think I continued to do cardio every day?... I had to shut cardio completely down and just eat, and eat, and lift, and eat. And so it's a sacrifice. Do I give people the visual whatever as close as possible of Goldberg or do I give them a new version in which I look like a cruiserweight and it's just different, man."

"Why do you think I wore a coat every time at first when I got back? The answer is I still had to train, man. I was still training... I believe it was much more important for me to be aesthetically what I was like in the past as opposed to a dude who could run around for 20 minutes. That ain't me."
