She’s the number one seeded player in Women’s tennis, and has a plethora of trophies and Grand Slams under her belt.

So it was little surprise to see Serena Williams showcasing her super fit body as she worked up a sweat during a run in Coral Gables, Florida on Monday.

And while the sporting star is famed for her athletic prowess, the 34-year-old was actually hard at work shooting a television commercial as opposed to training for a tournament.

Honored and Toned: Serena Williams showcased her super fit body as she worked up a sweat during a run in Coral Gables, Florida on Monday.

Filming a spot for Chase Bank, the 2015 Wimbledon Women’s Champion showcased her gym-honed frame in a sporty ensemble.

Donning a lightweight black sports T-shirt, which clung to her torso, the sporting icon showcased her trim midsection and toned arms.

Teaming her Nike tee with an equally athletic pair of three-quarter-length leggings, Serena made sure the lower half of her athletic figure was firmly on display.

Rounding her typically sporty wardrobe off, the athlete wore a pair of black and grey Nike running trainers.

Obviously not heading out for a real run, Serena didn’t need to accessorise her outfit with anything – but she did sport an iPhone strapped to her arm in a running band.

She wore her dark locks arrow-straight down to her shoulders in a centre-parting, making sure her hair didn’t obscure her features.

And with her tresses framing her striking features, the tennis icon opted to only wear a minimal selection of make-up.

Serena looked to be taking her stint in front of the camera in her stride, and was seen chatting away with the cast and crew in-between takes.

Speaking in an interview with Harper’s Bazaar in January, she addressed her confidence when talking about what makes a woman attractive, insisting that 𝓈ℯ𝓍iness comes from within.

‘Being 𝓈ℯ𝓍y is really about how you carry yourself. Strength and confidence equal 𝓈ℯ𝓍y,’ she explained.

Serena also stressed the importance of always being your authentic self – especially when dressing for a first date because ‘your true colours will show through in the end’.

‘I think that goes back to always being yourself from the beginning. Be confident of your inner strength and beauty, and that will be reflected on the outside,’ she added.
