Steph revealed on Tuesday that she avoided going to the gym for a month after she suffered from a sudden health concern while working out.

She took to Instagram with a video detailing the event which saw her become lightheaded at the gym when she was 11 weeks pregnant.

Unable to complete her workout, Steph said she returned to her office with a ‘migraine’ and ‘almost fainted’.

‘I am 15 weeks pregnant and the last time I went to the gym I think I was around 11 weeks pregnant,’ she said as she bravely returned to the gym a month later.

‘I definitely thought I was over that first trimester nauseousness and I thought I had the energy back to go to the gym.

‘Within round one I was already feeling really lightheaded but I thought I’d just be able to take longer breaks and take my time and still get through the workout.’

The KICPOD host went on to say her second round of sets is when she ‘started to see stars’ and became ‘concerned’ there was something wrong.

‘I felt really lightheaded at this point and decided it was probably time to stop even though I only got to round two,’ she said.

‘I took myself back to the office and as soon as I walked back in a migraine hit. It’s fair to say that because I haven’t been to the gym since.’

However, after taking a few weeks break from the gym, Steph has now returned to her regular sessions, revealing she was now able to complete her entire workout.

Showing off her baby bump as she donned form-fitting baby blue athleisure wear, Steph made it through scapular push-ups, ᴀssisted chin-ups and lat pull-downs.

Steph, who shares son Harvey, two, with husband Josh, finished off her workout with dumbbell 21s, standing flies and two 45 second planks.
