Jackie ‘O’ Henderson showed off her slim figure as she sweated it out on a tennis court on Saturday.
The 48-year-old swapped services with a mystery pal, with the pair swapping numbers after the session.
The radio star looked stylish in a simple black t-shirt, which was oversized and flooded her petite waist.
She added a pair of baggy dark shorts with white sneakers which she wore without socks.
Jackie appeared to go largely makeup-free for the outing and shield her eyes with designer sunglasses.
The media personality completed her look by pulling her blonde locks back into a ponytail.
Jackie recently reflected candidly on her weight loss journey.
“Last year I joined WW again because I wanted to get my health back in order and I know their program is working for me,” she said in a social media post.
“Losing weight was never about what I looked like in the mirror, it was more about an overall feeling of well-being and trying to get my energy levels back,” she continued.
“Five months ago, I was 18 kilos heavier and I had no energy. My health was suffering, so I decided to change my lifestyle completely.
Jackie said she lost weight because she incorporated daily exercise into her routine and ate healthier.
She also gave up alcohol, which the presenter said many of her followers might not believe.
Jackie added: “I have never felt better than I do now. I can honestly say that I feel happier and healthier than I was in my twenties and have more energy for myself and as a mum. (and dog mum!)’
Jackie previously gave her listeners insight into her diet.
She revealed on The Kyle and Jackie O Show that she regularly skips breakfast, a practice known as intermittent fasting.
Jackie also avoids carbs and satiates her hunger throughout the day by munching on pre-cut pieces of steak.
She resists splurging on high-calorie foods for lunch, opting to eat only “three small pieces of steak” and a few rolls of Vietnamese rice paper containing fish and cabbage.
For dinner, Jackie usually eats vegetables and a protein like chicken or red meat.
Between meals, Jackie feasts on smoothies and Starbucks Frappuccinos, a type of iced coffee drink.
The mother-of-one didn’t always follow such a restrictive diet.
In February, she said women’s day she used to gorge on pizzas, sausage rolls and microwave meals from the gas station before she took control of her health.
