I can't speak to the pga tour, but I got to see some LPGA players in Florida and here's what I was told and also witnessed. I'm the morning two hours of work on short game and putting. Grab lunch, work on full swing hour to two hours, then go play either 9 or 18.
Can't speak to the gym time, but I'd guess an hour a day in the gym.
Thanks. That confirms what I think they do on a consistent basis. It's a job (that I would love to try if I could go back 20 years with my current knowledge/electronic devices (Tman, K-Vest, AMM3d) and have my old body back.)
