One Direction's Niall Horan and Harry Styles

The One Direction hunk is keen to emulate The Rolling Stones frontman's dancing skills, and as a result has decided to copy part of his fitness regime following a chat with the music legend's long-standing trainer and physio Torje Eike.

A source told The Sun newspaper: “Harry wants a career spanning decades like Mick’s and to have that he recognizes that fitness, health and developing his body is the key.

“He spoke to Torje about Jagger’s intense routine of kick-boxing, running, weights and, most importantly, ballet.

“That’s the Achilles’ heel in Harry’s training. He can’t dance and neither can any of the 1D boys — their choreographer recognized early on that they shouldn’t dance on stage.”

While Harry and his fellow One Direction bandmates - Niall Horan, Zayn Malik, Louis Tomlinson and Liam Payne - have been hitting the gym hard during the current US leg of their 'Take Me Home' tour, the 19-year-old star is hoping his new hobby will help him to become more "graceful" on stage.

Ramzy Khachik said: “Nobody works harder than ballet dancers.

“It’s all about grace, stance and strength.

“Harry sees how supple Mick is, how he manages to stretch his body and do contortions.

“It’s a brilliant art form and will get more grace into his movements — if you’re graceful you can get away with minimalistic moves, which is what their choreography is about.”
