I am also having the forearm pain. I think from being a little tense and from playing for sessions that are too long. (I need to learn to relax and sit up straighter when I play as well.) Look under the ‘Skill Courses’ on the menu on the left of Tac’s main page. Tony has a section on daily stretches in there. I’ve been doing those and they help a lot! I also looked up exercises and stretches on youtube for ‘golfer’s elbow’, because I have some pain on the inside bony knob of my elbow. A lot of the exercises were similar to Tony’s and have been very helpful. Best of luck!
