Nick Willis' experience is starting to show as he prepares physically and starts to set himself mentally for the Rio de Janeiro Olympics later this year.
With his fourth Olympics still six months away, Willis is more focussed on next month's world indoor championships.

Willis says he's just enjoying being able to continuously enjoy improving as an athlete.
The Beijing silver medallist has flown back to the United States after spending several weeks in New Zealand over summer.
