Tiger Woods has again expressed a determination to return to the peak of his powers but knows he has "a lot of work ahead" as he steps up his recovery from back surgery.
The 14-time major champion's agent, Mark Steinberg, last week rubbished reports that the former world number one had suffered a significant setback.
Woods, 40, then posted a video of himself practising on a golf simulator, adding that he was "progressing nicely".
The legendary American, who has not played competitively since the Wyndham Championship last August, gave another update on his progress on Wednesday, while again stopping short of announcing a likely return date.
He revealed on his website: "As I announced last week, I am starting to feel a lot better. I have been chipping and putting at home, and recently started hitting 9 irons. That's been so nice. After all, Florida is the Sunshine State.
"My son Charlie and I compete in just about everything and have three-hole chipping contests. The loser has to do push-ups. My short game feels pretty sharp.
"The big thing right now is trying to get stronger and more flexible. Sitting out as long as I did, some weakening occurred, and I have a lot of work ahead of me.
"While there is no timetable on my return to competitive golf, I want to play this game at the highest level again. In order to do that, I have to get healthy.
"I've received many nice calls and texts from my fellow PGA Tour players and want to thank them for their support and encouragement. It's a fraternity out there, and we're all in this together."
