The Spice Girl, 48, took to her Instagram account to show off her stunning figure.
Victoria posted a snap of her in a black crop top and cycling shorts as she hit the gym.
Posh Spice left fans hot under the collar with her toned physique.
She told her 31 million followers that her workout with celebrity trainer Bobby Rich was designed to tone her legs.
It comes after The Sun exclusively revealed that Victoria would reunite Emma, Mel B, Geri and Mel C for the Spice Girls’ 30th anniversary.
The chart-topping supergroup are considering a headlining slot at Glastonbury’s Pyramid stage.
There are also plans for a one-off documentary featuring never-before-seen footage — with Netflix and Apple TV eager to snap up the rights.
Emma Bunton, 47, Geri Horner, 50, Mel Brown, 48, and Mel Chisholm, 49, have provisionally agreed to tour dates in 2024 — with recent absentee Victoria “bringing ideas to the table”.
A source said: “For the past few years the Spice Girls have still been operating day-to-day as a four but, for the first time in a long time, Victoria is now chipping in and happy to celebrate a landmark 30 years of girl power.
“Their schedules are pretty manic so getting them all in one room at any one time is hard. But over the past six months there’s been more contact as a five than at any time since the 2012 Olympics.
“Victoria will be 50 next year, and the girls turning 30 seems like two anniversaries too good to miss.”
