Michelle Bridges has some very impressive muscles.

The celebrity trainer and mum-of-one was spotted outside a supermarket in Kings Cross wearing a striped singlet, and flashing her incredibly muscular arms as she carried heavy grocery bags to her car, where partner Steve ‘Commando’ Willis was seen waiting.

She also had her trim and toned pins on display in a pair of tiny denim shorts.

It’s likely Bridges and Willis were shopping for supplies for their son Axel’s first birthday, which they celebrated earlier this week.
