Harry Styles showed off his muscular physique in a pair of tiny shorts as he headed out for a stroll through Mayfair on Tuesday.

The singer, 31, teamed the retro style red Adidas shorts with a graphic printed white sweater for his outing.

He completed his casual look by layering over a blue jacket and adding a pair of practical white trainers.

Harry, who was this week given to go ahead on his £30million super-mansion in Hampstead, listened to music while leaning against a fence.

He has been keeping a low-profile since wrapping his Love On Tour tour in July 2023, with it been more than three years since the release of his third album Harry’s House.

Prior to several sightings of Harry in London, the former One Direction star had largely disappeared from the spotlight.

He did however, surprise fans when he crossed the finish line at Tokyo Marathon last month with a time of 3:24:07.

The singer, who placed 6,010th of the 26,706 runners has clearly been working hard to beat more than 20,000 other runners across the finish line.

His PT, ex-commando Thibo David, has revealed Harry was ‘one of the fastest’ when he trained at his studio in London, even amongst a client base of professional boxers and footballers.

The former One Direction star has been working hard with his coach to achieve optimum results by running, swimming, weight training and mobility work.

Recovery sessions are also a huge focus, with ice baths, massages and stretching at the forefront.

In an interview with The Independent, Thibo explained his one-mile PB of 5min 13sec was ‘incredibly fast.

He added: ‘I train elite athletes, professional boxers and professional footballers, and I keep a leaderboard of their mile times in my studio. He was one of the fastest, only 14 or 15 seconds behind Granit Xhaka.’

Thibo built up Harry’s running in lockdown, taking on lengthy runs around London, but keeping his heart rate in zone 2.

‘We did a lot of dumbbell work on imbalances and stability with one-sided lifts like heavy kettlebell cleans, one-legged squats and lunges with the weight on one side to work on his balance, making him strong one side at a time and increasing his core strength,’ he explained.

‘Other days he would come in and we would just focus on mobility, or we might put some boxing in there depending on what he had coming up because he really enjoys that. We would mix it up a lot.’

On Sunday, Harry, who has kept a low profile since wrapping his Love On Tour tour in July 2023, took to the streets of the city to participate with fellow runners.

He logged an incredible time as he crossed the line in under three-and-a-half hours, beating more than 20,000 other runners.
