Thank you Ginny! All are great ideas.

Apathy and depression can be part of Parkinson's. An anti-depressant might help. Or if pain makes it hard to exercise, addressing the pain can help.

OTOH, if someone is not used to doing regular exercise or dislikes doing exercise for exercise sake (e.g. not a game or enjoyable activity) it can be hard to find motivation. Knowing that exercise helps slow progression doesn't seem to be enough for some people. (My husband is one.)

What works for us, most of the time, is if I do the exercises with him. He simply won't do them on his own, but if I ask, "Would you like us to do your LSVT-Big exercises now?" Or "Are you ready to walk the dog?" then he'll do them. A group class motivates some people. Those who do Rock Steady Boxing seem to really enjoy it. Finding an activity you really enjoy makes a big difference. Some like tai chi or yoga or ping pong. Any movement is better than none.
