Colson Smith joked he'd need to wear a fat suit as he returned to Coronation Street after losing a huge amount of weight in lockdown.
Colson, 21, plays Craig Tinker, and has used his time in isolation to get super fit, committing to a gruelling fitness regime.
As a result of his efforts he said he feels like he's lost "ten stone".
As he returned to set he shared a snap of his body before he headed off for a run - reports Mirror Online.
He captioned the snap with: "Starting the morning with a run. Quarantine daily run."
He added: "First day back at work. Like a kid at Christmas."
Colson's dramatic weight loss has prompted many Corrie fans to question how producers will deal with continuity as his character Craig takes on a different dynamic.
This could be answered by the announcement that a number of storylines will be scrapped so that the soap can begin again in a post coronavirus world, with new stories coming from that.
Colson shared the secret to his dramatic turnaround with his body shape in a video that he posted on social media last week.
In it, the actor can be seen working hard, swinging kettlebells above his head, doing curls with heavy dumbbells and slamming a weighted ball on the floor.
Andy Whyment, who plays Kirk Sutherland in Corrie, commented: "Looking absolutely mega pal well done."
Speaking on his podcast, Colson revealed that he might have to employ a fat suit to help his character Craig to keep his shape.
Colson said: "We are in direct continuity, but I've almost lost about ten stone since we left work so I'm not sure that [my hair] is going to be the biggest of their issues.
"I might be wearing a wig and a fat suit when we go back. Now we go to a purple shampoo, which almost makes it a platinum sort of colour, which basically takes the ginger pigment out.
"So the yellow-ness will go, and I will have a head of blonde hair, which I technically do now."
