Australian Commentator Peta Credlin in Two-Piece Workout Gear Flexes Her Biceps

Peta Credlin is flexing and showing off her muscles – in her workout gear. In a new social media post the Australian commentator, 54, gets real about building muscle in her 50s while showing off her body in a two-piece exercise set. "For those asking for an update – see what happens when your trainer @jameskellypt takes off to Italy for 5 weeks and leaves you in the hands of the master @coach_folino? Bit by bit we're getting there but not as easy in my 50s as before," she confessed in the caption. How does she approach diet, fitness, and self-care? Here is everything you need to know about her lifestyle habits. 

Strength training with her personal trainer is Peta's main form of fitness. "Halfway through the year and we're getting there @jameskellypt. It's all about the guns as you know 😂 and it's much harder now that I'm in my 50s!" she wrote in a post, adding that "weights" are a key part of her routine. According to the Mayo Clinic, strength and weight training help reduce body fat, preserve and increase lean muscle mass, and burn calories more efficiently. Strength training may also help you:

• Develop strong bones
• Manage your weight
• Enhance your quality of life
• Manage chronic conditions
• Sharpen your thinking skills

In the same post she emphasized the importance of getting enough protein. According to clinical trials, consuming more protein than the recommended dietary allowance not only reduces body weight (BW), but also enhances body composition by decreasing fat mass while preserving fat-free mass (FFM) in both low-calorie and standard-calorie diets.

The last part of Peta's approach to health? "Consistency," she reveals in the post. "The last one being the most important. It is the best mental health hours of my week," she says. 

Peta gets her steps in with the help of her pooch. "I'm just walking the dog," she says in a video. "A glorious Spring day walk..and a worn-out little man 🐶" she captioned another post. Going for a daily walk can be a game changer in terms of exercise, especially at a brisk speed. One study published in JAMA Internal Medicine found that walking at a brisk pace for about 30 minutes a day led to a reduced risk of heart disease, cancer, dementia and death, compared with walking a similar number of steps but at a slower pace.

Peta enjoys the perks of caffeine. Here she is about to take a shot of espresso with a piece of cake. According to the Cleveland Clinic, there are several benefits of drinking coffee in moderation. "It acts on your brain to improve memory, mood, reaction times, and mental function," they say, citing a study finding that caffeine can improve endurance and performance during exercise. It is also antioxidant-rich, can ward off diabetes, prevent neurologic disease, lower cancer risk, and ward off depression, they point out.
