have upped rpms to >80 which i can maintain for 15min. will gradually increase and report my results. using a recumbent. it's an uncomfortable pace, requires a lot of concentration and setting the resistence low. but it's certainly a more vigorous workout even with half the resistence i was using.
as an aside, my pd symptoms accelerated after i stopped playing/coaching soccer.

did the cleveland study really show brain changes via MRI?
