That's not gym attire! Frankie wears garish leggings as she continues to rehearse with The Saturdays for upcoming tour

Most people wear jogging bottoms for a workout at the gym, but not Frankie Sandford.

The singer was spotted arriving for a session today sporting a pair of bright red leggings with gold zip detailing.

Showing off her trim figure in the skintight clothing, she also opted against a pair of trainers and wore heeled buckled shoes instead.

Frankie - who makes up a fifth of popular girl band The Saturdays - was making up for lost time in the fitness department after almost two months off due to a mystery illness.

Teaming her stand-out leggings with a grey printed T-shirt and black biker jacket, the 22-year-old star kept her large sunglasses on at all times as she strolled arm-in-arm with her band mate, Mollie King.

However, Mollie had attempted to dress a bit more appropriately for their visit to the gym.

The blonde star teamed flip-flops and a T-shirt with a pair of baggy grey jogging bottoms, but she too finished off her look with a leather jacket and sunglasses.

The pair were laughing and joking as they prepared for their workout and 24-year-old Mollie looked happy to have her fellow band mate back by her side.

It was a very similar scene to yesterday when the girls were joined by the rest of their group - Rochelle Wiseman, Vanessa White and a pregnant Una Healy.

The band are rehearsing for their highly-anticipated, All Fired Up tour, which begins next month.

Stating that it will be strictly an 'arena' tour, the girls already have 11 dates confirmed and have revealed that they will be 'going all out.'

The band are no doubt thrilled to have finally been reunited with Frankie following a string of high-profile appearances in which the brunette was noticeably absent.

There was speculation that she had left the group after it was confirmed that she was admitted to hospital in October, but as she's been pictured rehearsing for the second day in a row it seems that Frankie is back and fighting fit.
