The 14-time Major winner also posted a video of his progress
Tiger Woods says he isn't setting a timetable on a return to competitive golf after having back surgery.
The 14-time major winner wrote on his official website that he is starting to feel a lot better, following the video he posted last week showing him practising on an indoor simulator.
Woods says he still wants to play at the "highest level" again.
"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," he said.

"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."
