Lewsey spent three weeks trekking in the Himalayas this summer

Lewsey, 29, has been shunted between full-back, wing and centre in recent seasons but wants to focus on securing one position in the World Cup squad.

"I don't care where I play as long as I have continuity," he told BBC London.

"It's difficult to set objectives if your parameters change every week so I've just asked for some consistency."

Lewsey returned reinvigorated from three weeks' trekking in the Himalayas to score 11 tries as Wasps won the Middlesex Sevens last weekend.

He was one of a host of senior players to opt out of England's summer tour to Australia to escape the rugby treadmill.

Lewsey had started 22 of England's 23 Tests since their World Cup win but a season marred by injury and a dip in form saw him dropped for the final 2006 Six Nations match with Ireland.

We've had a very disappointing few years with England which culminated in us being downright awful in the last Six Nations Josh Lewsey

"It's the first time I've had a pre-season in a long time. I actually had a chance to get the body right," said Lewsey, who has toured the southern hemisphere four times in the last three years.

"[It's] just getting back to enjoying the game and doing what you do well which is getting the ball in your hands and having a go at people and that's what you play the game for."

Lewsey was instrumental in Wasps' three straight Premiership titles from 2003-05 and Heineken Cup glory in 2004 and he is hungry for more domestic success.

But despite England finishing fourth in the Six Nations for the last two years, Lewsey is adamant that Andy Robinson's men can retain the World Cup.

I think England will be there or thereabouts at the World Cup and the nice thing is that most people have written us off Josh Lewsey

"We've had a very disappointing few years with England which culminated in us being downright awful in the last Six Nations," he said.

"That had its implications and there have been enormous changes behind the scenes but the guys feel enormously positive about the changes.

"New Zealand set the blueprint by blending this element of physicality with creative guile - that innate ability to put people into space.

"If you've got that blend, you're a very difficult rugby proposition to take on because you can play both methods and that's what we need to get back to.

"But with [new England attack coach] Brian Ashton coming on board with his yoda-like vision of how the game should be played, blended with [forwards coach] John Wells' pragmatism, you've got potentially a very formidable rugby environment.

"The talent is in England. The standard of club rugby will rise by resting a lot of the senior players this year and that will have a big, positive implication on the season.
