He's used to keeping himself in great shape after years as a top professional tennis player.

But now, sporting legend Mark Philippoussis is leaner than ever after taking part in the gruelling upcoming season of SAS Australia.

'Aftermath'

The 44-year-old took to Instagram on Tuesday to share a photo of the "aftermath" of his time on Channel 7's challenging reality TV show.

"Never been so excited to watch my ass get kicked!" Mark captioned the mirror selfie.

He showcased the physical toll his SAS stint has taken on his body, leaving his muscles toned and defined.

This is Mark's second reality TV appearance in the past year after he took part in the debut season of The Masked Singer in 2020. He was unmasked as the Echidna in the first episode.

Mark's fellow celebrity 'recruits' shared their praise and compliments for his transformation in the comments section.

"Absolute machine," wrote ex-footy star, Sam Burgess.

"Rigs of SAS calendar has started on [fire emoji]," said Home & Away's Dan Ewing.

"SAS - Super Ab Solutions!" chief instructor Ollie Otterton added.
