YouTube is great for PD warrior exercises and Tai chi. My Pd nurse introduced me to a physio who has just started out doing PD warrior classes. I had 2 private assessments with her (very expensive). Her classes are on when I'm not available unfortunately. Hopefully it will become more available through out the country.
Wildrover, that's great that you are doing pilates. It's great for the core and overall strength. I do yoga but should do more.
