Feeling chesty? Simon Cowell leaves Britain's Got Talent auditions in Cardiff carrying a set of exercise plates especially made to boost the chest muscles
He's renowned for his tight T-shirts and, of course, high-waisted trousers.
And now the secret of how he fills out his upper half, in order to keep his T-shirts clinging to his physique, is out in the open.
The X Factor judge, 50, was pictured leaving Britain's Got Talent auditions in Cardiff today carrying a gym bag with what appeared to be a set of workout instruments made especially for push-ups.
Revving up: The Bodyrev Perfect Pushups are rotating plates that users can place on the floor to improve the results of their chest exercises
Makers Bodyrev say their Perfect Pushup product offers users the chance to turn their homes into a gym and do the perfect push up.
The rotating pads are placed on the floor with the aim of reducing joint strain and engaging more muscle, accoring to their online advertisement "You will get measurable results in 10 work outs".
Cowell is famed for his love of T-shirts that appear to be moulded to his upper torso, and recently flashed his new, improved pecs while on holiday in Barbados.

The music mogul has stated in that past that his training regime consists of doing exercises at home and in his office.
He once said: 'I’d do 100 press-ups before I get in the bath in the morning, then at work after a meeting, I’ll shut the door and do more.'
In 2007 he vowed to shape up after seeing unflattering photos taken of him on holiday in December 2006.

The pictures showed Cowell with an out of shape chest, sporting what are commonly referred to as moobs.
In December 2007 he told the Daily Mail about the efforts he took to preserve his looks.
He said: 'I am vain but I cannot think of one person on TV who is not. It is the nature of the beast.
'I have had Botox but not in an obsessive way. I just like to take care of myself. I am eating a lot better and have cut out the chocolate biscuits and crisps.
'I work out, take lots of vitamins and think I look good for my age.'
