I have severe spinal osteoporosis; in addition, I had two years of severe upper back pain due to disc problems. Someone recommended Jan Golden for tai chi, and after a couple of sessions which concentrated on standing and posture, my upper back was (and remains) completely pain free.
Having continued classes for some months now, I notice a significant increase in strength in my feet and legs, as well as a huge improvement in balance. I feel stronger and more confident, and am less afraid of falling over. The changes in posture and emphasis on building strength have been very important for me.
Jan is an outstanding teacher and communicator, the classes are enjoyable, and the results have certainly exceeded my expectations.
