The former Celtic boss underwent the transformation ahead of his 50th birthday

Brendan Rodgers' incredible body transformation has been revealed by his former personal trainer, who has lifted the lid on how the football boss got into the best shape of his life ahead of his 50th birthday.

The former Celtic manager underwent a major fitness overhaul in 2023, with the before and after photographs showing a noticeably leaner physique and defined abdominal muscles.

Now, the trainer who worked alongside Rodgers during the three-month transformation has shared the results and revealed the motivation behind the Irishman's decision to focus on his health.

Rodgers, now 53, was managing Celtic at the time, having returned to Parkhead for a second spell in the summer of 2023.

Despite the demands of leading one of Scotland's biggest football clubs, the manager made time to work on his own fitness as he approached the milestone age.

His personal trainer, Matt Hall, recently took to Instagram to share photographs showing the difference in Rodgers' appearance following their work together.

Alongside the images, Hall praised the manager's commitment and revealed how determined he had been to reach his goal. He said: "I had the pleasure of coaching Brendan Rodgers as he approached his 50th birthday.

"Despite the demands of managing at the highest level of professional football, Brendan made his own health and fitness a priority.

"His mindset and discipline throughout the process were impressive and played a huge part in achieving his goal of reaching 50 in the best shape of his life."

Hall had also shared details of their training partnership in a post dating back to 2023, revealing that he had been working with Rodgers for a three-month period leading up to early December that year.

The timing means their fitness sessions took place during Rodgers' return to Celtic, with the manager balancing his training commitments alongside the pressures of life as a manager.

The before and after pictures show a striking difference, with Rodgers appearing considerably leaner in the later photograph, sporting a toned physique and clearly defined six-pack.

The transformation came as the manager prepared to celebrate his 50th birthday, with Hall explaining the discipline and dedication required to achieve Rodgers' goal.

Rodgers has since moved on from Celtic for a second time, leaving the club in October 2025 before taking up his current role with Saudi Arabian side Al-Qadsiah in December.
