Constant fatigue is a part of Parkinson's , exercise is the one thing that a lot of literature exist about the positive effects it has on Parkinson's disease progression. Maybe think about that being possible and the effort you put in will be rewarded in some way. It will be difficult and require determination ,but gain strength knowing others are also experiencing similar struggles.

When I feel like I can’t exercise, I know I need to and I make myself get up. Once I’m up and moving I feel better. Once I’ve completed the exercise I feel great. The first move is the hardest, but you can do it!

Me too. It's really hard to get out of the chair sometimes. I find playing loud music helps me get up and do some marching on the spot or dancing. Currently Bob Marley does it for me! Good luck 😁

I agree. Am committed to water exercise but, struggle to get there

I can relate. I often find I am quite lethargic the first 30 min s after I tailed my meds. But knowing this allows me to plan ahead with something I want to do
This is usually all it takes to get me active since I usually find activity so much more enjoyable.
