And Australian Idol runner-up Shannon Noll, 47, proved hard work really does pay off when he stripped off for a shirtless gym photo on Monday.
Taking to Instagram, the singer shared a photo of himself looking insanely ripped as he flexed his muscles next to gym equipment.
His bulging biceps, chiselled abs and jutting muscles were on display, while his face was hidden under the shadow of a baseball cap.
Shannon also showed off a glimpse of his extensive tattoo collection, including a striking design on his shoulder and a Southern Cross ink on his chest.
