First Lady Fitness: Melania Trump's Brutal Exercise Regimen and Very Strict Diet That Help the Former Supermodel Stay In Top Shape and 'Avoid Plastic Surgery' Revealed

First Lady Melania Trump has been able to maintain her enviable model figure throughout the years, but it isn't without plenty of hard work and sacrifice, RadarOnline.com can reveal.

Trump, 56, has a diligent routine that she follows involving combining a favorite sport with a secret weapon that has allowed the Slovenian-born beauty to constantly tone her incredible legs without having to go for runs or hit a gym. She also abides by a strict diet.

In a 2016 profile, it was revealed that Trump used ankle weights to walk around her New York City penthouse, helping her keep working her leg muscles by just going about her daily business at home.

She also enjoys playing tennis as her favored form of fitness. The sport comes easily as her husband, President Donald Trump, has plenty of clay tennis courts at his beloved Mar-a-Lago estate in Palm Beach, Florida.

The couple enjoy spending time in the winter months at the home and club that has become known as the "Winter White House."

Melania also is a fan of Pilates, which helps elongate muscles and develop core strength. She's said to enjoy the practice as she's able to do it from the privacy of her home.

As far as Melania's diet, she revealed in 2016 that she always eats seven pieces of fresh fruit each day, with apples and peaches said to be her favorites.

She starts her day with a tasty smoothie, going so far as to share the recipe with fans on Facebook in 2013.

"Got many requests from you for recipe of my every day delicious and healthy breakfast," she noted before revealing she mixes "all fresh and organic: spinach, celery, carrots, blueberries, apple, orange juice, lemon juice, fat free yogurt, olive oil, flex seeds, omega-3, vitamin D."

While she is a huge fan of fruit, Melania has an aversion to certain vegetables. She made it known that she can't stand onions and artichokes during a 2005 TV appearance with domestic diva Martha Stewart as the pair made meat loaf.

Melania keeps calories in check by monitoring the portion sizes of her meals, and she reportedly likes the healthier dark chocolate as an indulgence when craving something sweet.

While the two-time first lady keeps her social media posts professional these days, past snapshots showed Melania enjoying an avocado salad with lettuce and cherry tomatoes, salmon and edamame, and colorful fruit plates including pineapple, banana slices, raspberries and blueberries.
