Daly finished 32nd in the USPGA at Southern Hills

World number one Woods, who won the USPGA on Sunday, said his opponents could have combated Tulsa's heat better with a fitness regime like his.

Daly, who weighs 100kgs and has had well-documented alcohol problems, briefly led at Southern Hills before fading to tie for 32nd place.

But he said: "I did better than most players last week who do work out."

Speaking on the eve of the European Tour's Scandinavian Masters in Sweden, Daly added: "I don't think it matters if you work out or if you don't work out.

"I'm used to the heat. Fat boys like me can get through the heat.

"I tried but every time I worked out I threw up and I thought to myself that you can get drunk and throw up, so it's just not for me.

"I'm flexible enough, there are probably some things I could do to keep my flexibility up, but I'd rather smoke, drink diet Cokes and eat. I get enough exercise walking five or six miles a day."

Daly, who won the 1991 USPGA and 1995 Open, admitted there were some aspects of 13-time major champion Woods's game he would like to copy.

"I think the thing that separates Tiger from everybody is that he makes putts more than we do," said Daly. "Right now he is like a one-man field."

Alongside Daly, three other major champions will compete at the Arlandastad Golf Course.

Former Open champion Paul Lawrie of Scotland, last year's United States Ryder Cup assistant Corey Pavin and former USPGA champion Jeff Sluman are all playing in Sweden.

Outgoing US Ryder Cup captain Tom Lehman was set to play but withdrew with a wrist injury on Wednesday.

Britain's defending champion Marc Warren will play alongside Daly and tournament host Jesper Parnevik in the first two rounds.
