Mark has a fit set of muscles

Mark Wright and his younger brother Josh clearly enjoy a bit of sibling rivalry.

The lads’ mum Carol posted a Twitter snap of ex-TOWIE star Mark, 27, doing press-ups opposite footballer Josh, 24, at the family’s Essex home yesterday. 

‘Just walked indoors to see @markwright_ & @joshwright4 competing at press ups in the garden. Just like the old days,’ Carol captioned the shot.

Mark – who also has older sister Jess, 28, and youngest sibling Natalya, 13 – is close to Josh and the pair often Tweet about the times they hang out together.

In February, Mark revealed that he’d asked Josh to be best man at his wedding to fiancée Michelle Keegan.

Fans reckon Coronation Street actress Michelle, 26, is a rather lucky girl after seeing Carol‘s picture of Mark working out.

‘ooooh nice view x,’ Tweeted one.

Another wrote: ‘looking good :)) who won?’
