Dr. Rick. Good general advice. I have no medical issues other than occasional back pain. 55 year old male, 6'1, 220 lbs, so I am overweight. Not an athlete, but not a couch potato. Jog/walk/bike 3x/week
I can't induce the occasion other than stopping my exercises for several days. I'm guessing there are some general principles; I hear bucket seats are bad because buttocks is lower than knees.
Do you have any more concrete advice? Web site reference(s)?
