In an exclusive interview with New Idea, Tammy revealed the trick to getting a body - or booty - like hers.
"Whether it’s a gym workout or HIIT home workout I always try to fit it [exercise] in when I can," the Gold coast celebrity said.
Tammy claimed to train three to five days a week doing minimal cardio and heavy weights - but she also says there are some simple tricks time-poor people can do to tone up as well.
"I will often do some workouts from my at-home booty program – you only need dumbbells, or I will do a HIIT workout in the lounge room."
She also detailed her nutritional plan, emphasising that she maintained a protein-rich diet.
"I eat every two to three hours," she explained.
"For breakfast, I usually eat oats with Women’s Best protein powder. I always have protein shakes after my workouts and love to eat fish, chicken, turkey, beans and vegetables," she added.

The mother of two encouraged other mums to find the time to exercise, even if it's a quick session in the lounge room.
"I honestly feel better when I get my workout in, less sluggish and I find it easier to keep up with my kids," Tammy said.
"I recently posted an at home HIIT workout on my YouTube channel. I did it in the process of moving house when I was really feeling the need for a pick-me-up.
"There was a lot going on that week and I was feeling it, I decided to film and post it on my channel to show how I can fit in a quick workout throughout your day."
