If you thought living through lockdown was tough, spare a thought for professional athletes. While most of us gave in to the temptation of regular snacking and lazing about on the sofa all day, sportsmen and women didn't really have that luxury. They needed to stay sharp in quarantine in order to hit the ground running when the action returned. Some did exactly that. Last month, football fans were quick to notice Bayern Munich's Leon Goretzka had undergone a crazy transformation while in lockdown. Before the break, he appeared to be a small, skinny midfielder but emerged a couple of months later with a shredded, stacked physique.It seems Goretzka wasn't the only footballer to hit the weight room during his time off. Shanghai SIPG forward Hulk has recently shared a number of images on social media and he looks in the shape of his life ahead of the Chinese Super League restart. Hulk has undergone an impressive transformationCheck out some images of the Brazilian showing off his impressive body:Hulk looks stacked these days.

But just look how much better he looks now, compared to 2015: Hulk looks very different these days.

Hulk may be preparing for the Chinese Super League season to kick-off, but he's actually confirmed he'll be leaving Shanghai later this year.  

"My contract ends in December. We already had a meeting and I said I don't want to extend," he told Globoesporte.

"Now it's raining proposals from several countries. It's true that among them are many of Europe's big clubs, competing in the Champions League, and also Brazil. 

Hulk will leave China this year

"Even from China, but I don't want to stay here."

Given the 33-year-old looks in the shape of his life, it's hardly surprising he has offers to return to Europe. If he does, we'd love to see him rip up the Champions League once again.
