Elyse Knowles flaunts her trim post-baby body at the beach with her five-month-old son Sunny

Elyse has shown off her impressive slimmed down post-baby figure at the beach. 

The model posted a picture to her Instagram on Wednesday, where she is seen standing in the water looking trim and toned in a pale green bikini.

Elyse’s five month old son, Sunny, is adorably sitting on his mother’s shoulders and rocking a brown cap.  

‘Winter adventures with my man,’ the 28-year-old wrote in the post. 

Followers of the model wrote endearing comments alongside the photo. 

Former AFLW player Amelia Mullane wrote, ‘He is so big already, time flies.’

‘Little dude,’ commented fellow model Brooke Meredith, adding a series of hearts. 

‘That’s a very, very risky move,’ wrote another follower with a laughing face emoji, referring to Sunny sitting on her Elyse’s shoulders.  

Elyse and her fiancé Josh Barker welcomed their first child together, Sunny, back in February. 

The model has been getting straight back in her fitness routine since the birth. 

Earlier this month she posted a photo in a green crop-top and leggings, flaunting her toned midsection. 

In June, Elyse was seen doing a workout at a Pilates class in Byron Bay.

In a workout video, she showed off her lean body and upper body strength as she pulled herself up on two metals bars as her ankles sat in a pair of straps.  

The model was also completing a range of boxing exercises.
