Robbie has clearly undergone a gruelling workout regime to develop such impressive biceps, abs and chest muscles.
As well as showing off his rock hard shape the snap also highlighted the singer's extensive body art.
Robbie is expecting the arrival of his first child any day now and he didn't appear with the rest of Take That at the Olympics closing ceremony because he wanted to be with wife Ayda.
Ahead of the concert a spokesperson for Robbie told MailOnline:'They were initial discussions but he just can't do it because his wife is about to give birth.'

Not so in shape: Robbie hasn't always been in such toned shape
Robbie revealed he and wife Ayda were expecting a baby back in March and it's clear he can't wait to meet his daughter.
The singer recently tweeted a picture of his wife showing off her growing baby bump with the caption: 'My two girls!'
Robbie's band mate Gary Barlow suffered a personal tragedy earlier this month when his daughter Poppy was stillborn.
The heartbreak came just days after Mark Owen welcomed his third child daughter Fox India.
