@ray666 Thanks for your encouraging words and recommendations Ray. I looked up Leslie French- she's energetic, encouraging and pretty buff! And you're right, all of these classes are so good for the spirit. For balance work, I like this free practice by Dr. John Saunders which is actually for vestibular rehab. It's quick and complete. I'll do it every day for a couple of weeks then take a break for a week or two (okay, sometimes for a month!) and then pick it up again. I think you're right, consistency is key. Thanks for your reply!

If you're interested, you can find that practice here, and there's a PDF in the comments if you want to print out the exercises:
