The Wales talisman is desperate to play in his nation's first appearance at the tournament since 1958 and says his fitness plan with Los Angeles FC will leave him in the right condition.
Bale said: "We have a plan in LA with what we're doing.
"We're not straying away from it too much. Every footballer wants to play as much as they can, but we're being clever and building myself up for the last important part of the season.
"Hopefully that should put me in great shape for the World Cup. I think I'll be a lot fitter. I haven't played 90 minutes yet, which is what I'm building up to."
He continued: "We're on a good path to where I want to be. Of course I want to play 90 minutes as much as I can, but I understand I need to build up to that because I haven't done it an awful lot in the last few years.
"The most important thing for me is to take each week as it comes.
"Hopefully that will be good enough for me to help LAFC and, ultimately, be ready for the World Cup."
Bale moved to the MLS after leaving Real Madrid this summer and says he has happy with life in Los Angeles.
He said: "I am very happy. My family are settled there, which is a big part, and the fans have been really supportive.
"It's taken a little while to get everything sorted, but I am playing games and have been training for the last 10 weeks and getting stronger.
"We now have an important stretch of games in the MLS and, after that, my attention will turn to the World Cup.
"The plan is just to be 100 per cent to help LAFC first and foremost. Ultimately, that will lead into me being 100 per cent fit for the World Cup."
