Jana Pittman is undoubtedly one of the strongest women to take on the SAS Australia course after having given birth just six months prior to filming.
The Olympian-turned-doctor and her husband Paul Gatward, 52, welcomed Charles Brian Pittman-Gatward in November last year.
Charlie, as his siblings call him, is adored by his older half-sisters Jemima, four, and six-year-old Emily, who were both conceived through the same anonymous sperm donation.
Jana also has a 14-year-old son, Cornelis, from her first marriage with former coach Chris Rawlinson.
After the birth of Charles, the former Olympic hurdler admitted she used to get worried about how she'd make room in her heart to love another baby.
"But I've worked out you don't carve your heart into portions for each, you just add another piece to it, and I fell absolutely in love with my Charlie immediately," she said.
"He's the easiest baby I've ever had and he's tolerant of being squished by the girls!"
While Jana is best known for her decorated Olympic track and field career and now has a hectic schedule as an obstetrician, at home she's simply "Mum" to her adoring kids.
Take a look at all the sweetest snaps of Jana and her brood.
