"Jan is on the right track. Everything is guaged at peaking for Los Vegas and we're on target," McNamara said.
Dixon and McNamara have worked together for a decade. She's won numerous high profile titles at competitions in New Zealand, Australia, the US and at the worlds in Dubai last year.
"We prefer the natural competitions where there are no drugs. We've got the New Zealand nationals in Napier at labour Weekend to put the final polish on. The nationals are not natural competitions, but we've beaten these guys before," McNamara said.
In typical modest fashion Dixon conceded she was "slowly getting there" when asked if she felt like she was peaking at the right time.
"We'll get the nationals out of the way first and then focus on Los Vegas - I'm getting there slowly," Dixon said yesterday.
Meanwhile, fellow City Gym bodybuilder Krista Adams came second in the women's figure competition in Wellington at the weekend after 11 years away from McNamara's coaching influence.
"Krista won as a junior under me 11 years ago and then went overseas and had children before returning to me this year," McNamara said.
