Gold Coast CrossFit trainer Revie Schulz has posted a video of herself weight training at 26 weeks pregnant.

The 24-year-old performed a series of squats while lifting 40 kilogram weights, and captioned the clip: 'It felt good to have some weight on the bar today'.

'It was super hot so I stayed super hydrated, next to the fan and had a wet towel to keep my body temp [sic] low,' she added. 

While a few of her followers questioned whether the workout was safe, a number of others were quick to support her.

'She lifted like this before, I think as long as your body is used to it and you have doctors clearance, it's okay! You shouldn't like, jump into a brand new lifting routine,' one of her fans said.

'It's safe because she knows what she is doing, is listening to her body, and isn't doing anything she hasn't done before,' said another. 

'This isn't her max weight. It's a complete myth that a pregnant woman shouldn't lift weights. If she was high risk, it would be a different story.'

In response, Ms Schulz wrote: 'Thanks for saving my breath'. 

'Always makes me hesitate to post because someone will question my intentions with my baby, it's nice to know people have my back.' 

Ms Schulz previously told Daily Mail Australia she had reduced the intensity of her exercise routine by 50 per cent and modified her exercises daily, or even hourly, in keeping with how she felt.   

The video came after Ms Schulz defended fellow Gold Coast fitness guru Sophie Guidolin who became the subject of online trolls after she posted her own weight training photo while 26 weeks pregnant with twins.

Ms Schulz has said that she wanted to support women like Ms Guidolin and The Biggest Loser's Michelle Bridges who copped flak for continuing to exercise throughout their pregnancy.
