Breakfast show host Nick Grimshaw is undergoing intensive training in an effort to set a new world record - for twerking.

The BBC Radio 1 star is practising to establish a duration record for the dance craze by constantly wiggling his hips and thrusting his bottom out for an entire hour.

He aims to set his record beginning at 8.30am next week, on September 30, with live coverage during his programme as an official from Guinness World Records monitors his progress in the studio.

Grimmy is limbering up with a tough regime of squats, and tutoring under the eye of an expert fitness teacher.

He said: "I can't wait to be etched into the history books for such a noble, worthwhile cause. Twerking has always been close to my heart... and a**e."

Guinness World Records adjudicator Anna Orford, who will oversee the attempt, said: "Twerking for a whole hour is no easy feat and Mr Grimshaw will have to seriously prepare if he wants to achieve this official Guinness World Record title. We wish him luck."

Earlier this year Grimmy tackled other feats of endurance by cycling in a perspex box for 12 hours outside BBC Broadcasting House for Sport Relief, and accompanied Davina McCall during a running stint on her 500-mile triathlon from Edinburgh to London.
