To my surprise I read the other day from a physical therapist that swimming, except for good cardio benefits, is not as good as I thought it was for PD's as long as you practice all swimming styles. One style will not suffice. Same with stationary bicycle. He meant "learning" but it was not clear to me what kind of learning skill he referred to.

I also read from another source riding a real bicycle is good for balance because it forces you to direct your attention around.

I have read about contradictory results as far as weight lifting.

The only exercise I currently practice is my daily hourly walk in the forest at 2,900 meters above sea level (I live in the Andes). I walk at a fast pace and since terrain is irregular I guess this contributes to brain's plasticity for balance. In addition, since I walk with a wooden stick, this forces me to move my arms (also a weapon. I had to defend my dog the other day against the attack of an aggressive Akita dog. Mine is an 11 year old peaceful Golden Retriever). The way I see it, we, human beings, were designed to walk so it won't hurt if I keep walking, like Johnny Walker.

What confuses me is that most doctors recommend either exercises or sports they don't even practice without realizing themselves the real benefit for their own (dancing, yoga, taichi).

I tried once yoga and deeply relaxed and fell asleep in the middle of the class. Found yoga as boring as listening to a chess game on the radio.

Have you tried Taichi? Supposedly, good for flexibility.

It would be nice to hear your comments.
