Max showed off the results from his workout in a series of photos and videos posted to Instagram. The 25-year-old has been training hard at Intensifit, a team of personal training specialists in Manchester.
Posing shirtless, Max flexed his muscles while telling fans: "Who's ready.... #lunch." In the same photo posted to Twitter, he added: "I was born with it.... Moulded by it…"
A video also shows Max hard at work in the gym as he's put through his paces by a personal trainer.
Max's workout comes as he recently unveiled his new image, sporting a full set of hair, ditching his trademark skinhead look.
Over the weekend, The Wanted performed their last ever gig at the Fusion Festival in Birmingham on Sunday 31 August, before going on an unspecified "break" as a group.
The boys - Max, Nathan Sykes, Siva Kaneswaran, Jay McGuiness and Tom Parker - announced their decision to take a hiatus in January.
However, only four members performed on Sunday, as Nathan was forced to pull out of the concert due to other work commitments in the US.
At the time of announcing their break earlier this year, The Wanted insisted it wasn't a split, telling fans that "it is not the end", but revealed plans to "pursue personal endeavours".
Shortly after, Max explained in an interview: "Our personal lives drove us apart."
While Nathan is thought to be pursuing a solo career, Max has been focusing his attention on acting, and has already auditioned for roles.
