I have very bad arthritis in my right knee and I spent about 12 sessions with Kathryn Weegar going over various exercises to strengthen my knee. I am very happy to report that my winter sport activities, skating and skiing, have been pain free; no knee braces required and tremendous endurance in my knees. This is the best my knees have felt in years! I am not even thinking of knee replacement at this time thanks to Kathryn’s excellent program. Thank you!
