Spice Girls star Geri Halliwell has admitted that she keeps her super-trim figure by practising anti-gravity exercises.

Speaking to Britain's Daily Mirror, she explained that she likes to hang upside down on a swing-like device and believes it helps keep the pounds off:

"I do yoga once a week as well as the swing. It really helps get a great core, and is a fun workout. But it's not easy to master straight away - you need to be quite flexible."

She continued: "I did it for 20 minutes this morning. I hold really, really light dumbbells in each hand, set the treadmill on a really steep incline and then sing while power walking. It's quite tough. I go through all my songs, belting them out, and find it really helps with my fitness and my nerves ahead of big performances."

The singer recently performed as a solo artist for the first time in 7 years and after her set she tweeted: "Amazing to perform,1st time as a solo artist in 7 years,especially for @BCCare inspirational people!"
