Ciara’s personal trainer Gunnar Peterson shed some light on how the mother-of-one does it.

'When you say she's working out every day, that sounds like it's crazy but it's not,’ he told People in September. 'It's a ritual. She's showering every day too. She's not destroying herself.’

He added: 'She's working hard, she's getting it done, she's eating properly, she's getting sleep while she can, and so she's getting leaner and stronger. That's the way to be the best mum.'

The celebrity trainer enlists a variety of exercises to firm up and tone the new mom's curves.

‘The typical workout is that it’s not typical,’ he said. ‘Depending on where we are in the week, there’s a focus on pushing movements, pulling movements.

'There’s lower body, there’s working different planes of motion, whether it’s front to back, side to side rotation.’

Meanwhile, Ciara has something else to celebrate as she is reportedly back together with the father of her child, rapper Future.

The singer split from the hip hop star following allegations of an 'ongoing affair with his stylist, according to several reports.

However, according to TMZ, the couple are now back living together, due to Ciara 'feeling strongly about her son needing his father around 24/7.'
