Tyson Fury is back in training ahead of his rematch with Wladimir Klitschko in Manchester on July 9.
The WBA and WBO heavyweight champion weighed in over three stone heavier than his fighting weight against Klitschko on his first day at training.
Fury tipped the scales at over 20 stone - 45lbs heavier than when he outpointed Klitschko in November to end the Ukrainian's 11-year reign as champion.
"Got a whopping 3:stone 3 pound to shed," Fury revealed on social media. "First day is going to be very hectic, it's going to be hard, the first week I anticipate will be mega hard, I'm expecting a very hard camp to be ready for July 9th."
Fury (25-0, 18KOs) promised to keep his followers updated with his battle of the bulge and urged people to join him in his quest to lose the excess weight.
"This is how it works, you train lose weight post before and after pics, we can talk it through, I'll give advice," he added before posting a picture of his lunch.
Fury later revealed his first day back at work involved 60 minutes on cross trainer, a six mile run followed by four rounds of sparing.
The 27-year-old is training alongside fellow undefeated heavyweight and cousin Hughie Fury, who faces 'Big' Fred Kassi at London's Copper Box Arena on April 30th.
Klitschko, meanwhile, is already four weeks into his training camp as he bids to regain the titles at the age of 40.
"I keep pushing forward and can't wait to get back in the ring with Fury #nowmorethanever," he posted on Instagram last month along with videos of him training.
