Woods returned to golf this season and has stunned many with his progress back towards the top.
The 14-time Grand Slam champion has been selected by Jim Furyk for the Ryder Cup later this month and he has risen up to 21st in the world rankings.
He is yet to win but finished second in the PGA Championship and tied at the Valspar.
The 42-year-old has managed six top 10s and is 20th in the FedExCup rankings.
But Tiger Woods thinks he needs to add another level of physical strength to his game and already has his plans in place for the offseason.
“I’m going to take a long break after the Ryder Cup and we’re going to evaluate things but, more importantly, I need to start really lifting and getting after it and getting stronger in certain areas because playing every single week seems like every single day is maintenance at this point, war of attrition,” Woods said.
“What you do in the offseason is what allows you to maintain it through the year especially on the backside of the year and I really didn’t train for all this.
“Because I didn’t know how much I was going to be playing. I was just trying to play.
“So, next year I have a better understanding of what I need to do and this offseason will be very different than it was last year.”
Woods finished tied sixth at the BMW Championship last weekend, shooting eight-under in the opening round to share the lead with Rory McIlroy after day one.
But he slipped away with a 70 on day two and never really got back in the fight despite a 66 and 65 on days three and four, finishing three shots behind Keegan Bradley and new world no 1 Justin Rose.
Woods will play two more events this year – the Tour Championship and the Ryder Cup – before taking his break to hit the gym.
Early this year, during the Valspar tournament, Wood recounted his old routine.
Well, I used to get up in the morning, run four miles,” Woods said.
“Then I’d go to the gym, do my lift. Then I’d hit balls for two to three hours.
“I’d go play, come back, work on my short game. I’d go run another four more miles, and then if anyone wanted to play basketball or tennis, I would go play basketball or tennis.
“That was a daily routine. I’m not doing any of that now.”
