The mum-of-one has shared before and after images with a few inspiring details about how she got in the best shape of her life after gaining 31 kilograms during pregnancy.
"I look back at some of my pictures and think WOW I fucking did that," Melissa wrote. "I’m really hard on myself most of the time and don’t really stop to think..."
Melissa says she started from nothing – no trainer, no guidance, no knowledge – while working full time and parenting.
"I never worked out or played a sport so I had zero Athleticism. I STARTED FROM NOTHING AT THE AGE OF 28! I was broke and lived to pay my rent and buy cheap groceries. I did my fucking best is all I knew. I truly did."
Melissa's main message has always been – persistence pays off.
Instead of ploughing through workout programs looking for quick results, "commit to a more sustainable regimen for one year before you entertain anything else," she's previously advised.
"IT TAKES YEARSSSS OF CONSISTENCY!!! IMA SAY IT LOUDER FOR THE PEOPLE IN THE BACK! YEARSSSSS OF CONSISTENCY. So before you quit ask yourself if you ever really started!"
When it comes to food and fitness tips you can incorporate into your own routine, Melissa told CNBC she practices intermittent fasting. Her eating schedule isn’t “super structured,” she says, but her first meal of the day is usually around noon, after her workout.
“I like to fast during the day because I tend to eat more late at night, when I get especially hungry,” she says.
Her workouts mostly involve lifting, with minimal cardio.
“I usually do legs twice a week or every three days,” she says, “but it’s usually the same thing every week.”
“I try to walk 10,000 steps a day. That’s pretty much my cardio.”
