Fitness star Tiffiny Hall on how she dropped 25kg a year after giving birth

A year after giving birth to her son, trainer Tiffiny Hall has shared how she regained her health and fitness.

Speaking to Sonia Kruger and David Campbell on TODAY Extra this morning, the former Gladiator explained how she managed to drop 25 kilos after a difficult pregnancy.

While pregnant with Arnold, her first child with actor Ed Kavalee, Hall was frequently ill and unable to follow the healthy diet and fitness plan she had counted on. She told the TODAY show earlier in the year, "I had no control over my hormones or my cravings… I kept sending my husband out for sausage rolls and other salty foods."

As a result, the former Biggest Loser star ended up gaining 30 kilos. She struggled to do one push-up.

To ease back into exercising, Hall used her own TIFFXO workout program at home. "Working out at home with Arnold was the only way I could work out in the beginning," she said.

This, combined with a healthy diet, helped her drop the 25 kilos within 11 months.

"I feel strong, I feel fit. I'm not back to my pre-pregnancy weight, I'm actually heavier because I've put on muscles and I'm feeling really strong," she told David and Sonia.

The key is to be patient with your progress. "Be gentle with yourself and take your time," she said. "It didn't take overnight for me. It took 11 months."

Hall also urges new mums not to forget what their body has been through.

"After you deliver the child, it's like major surgery, isn't it? There's recovery and there's rehab. What surgery do you have where, weeks later, you're expected to bounce back and be in a bikini?" Hall said.

The 33-year-old has been candid about her journey on Instagram, posting frequently about how her body has changed over the course of the last two years.
