Whitlock finished with a score of 90.631 which comfortably put him ahead of Scotland’s Daniel Keatings while his English team-mate Nile Wilson completed the podium.
“The main aim was to go and perform clean routines and I’m so happy that I managed to do that on the day,” Whitlock said.
“I wasn’t paying much attention to the scores, I wanted to have clean routines and that was it so to have that comfortable margin at the end felt really good.
“I can’t actually explain it, it’s a crazy thing. Even before the routine I was so nervous and to stick the landing (on high bar, the final apparatus) like that was amazing.”
Whitlock won three medals four years ago in Delhi but has worked hard to transform himself into an all-around gymnast since.
“Since London 2012 all-around has been a massive target so to pull this off is massive for me,” he added.
“It’s a big marker for the world championships, experience-wise and confidence-wise it gives me a big push to that.
“I will be training really hard and hopefully I can get some more skills in there which would be great.”
