I was wondering...does anyone have a good strategy for upping your heart rate through exercise? Do you use a heart rate monitor? I imagine that starting slow and proceeding in small increments makes sense. I'm not there yet, but the walking has been going well (have gone for 2 walks / day each of the last few days). Eventually I would like to try exerting myself a bit more, whether through faster walking, swimming, stationary cycling, etc.

The irony is that for non-PCS sufferers, aerobic exercise can be so beneficial for the brain (for a good book on the topic, see Spark by John Ratey). Whereas people with PCS, who could use these brain benefits more than most, often experience symptoms from exercise.
