The Essex star lost a massive one and a half stone while competing on the BBC One dance competition, which ended in December, and now he wants to get his old body back.
Mark shared an image to Twitter last night showing fans the differences in his body from before and after Strictly.
"I need to get back to myself," he said, adding the hashtag: "No pain, no gain."
"First time back in the gym doing weights since before Strictly started four months back. 1.5 stone lighter and I am lifting half the weight… This is going to be an uphill battle!!"
Fans were quick to tell Mark he looked rather good either way (we agree!), with one saying: "Hard work and dedication pays off."
Another joked: "Who cares? You have Michelle Keegan!"
Mark and former Coronation Street star Michelle will marry later this year. They've just returned to the UK from a holiday to Dubai where no doubt they were reminiscing about Mark's romantic proposal there back in 2013.
Michelle was Mark's biggest champion on Strictly, and recently said how proud she was of his success on the show.
Despite never dancing before, ex-TOWIE star Mark made it through to the show's final, where he finished in fourth place. Michelle gushed: "I'm SO proud of my @MarkWright_ I just want to say thankyou so much to u guys out there that helped him on this journey. #soemotional."
