I box twice a week and it helps immensely with my PD

My husband just started rock hard boxing and is showing some improvement in his balance and he loves the fact he thinks he’s Rocky

There seems to be a lot of shoulder problems with PD. I box twice a week with my PD group and it has helped hugely.

I've wondered the same thing, however, i did find a massage therapist who has helped tremendously with my joint stiffness. Last fall my left shoulder felt "frozen" and my left wrist ached all day. Megan (my miracle worker) was able to improve the range of motion so now I see her once a month.
